Fujian tulou

Fujian tulou are unique multi-story earthen buildings constructed primarily by the Hakka people in the mountainous southwestern region of Fujian Province, China, between the 15th and 20th centuries. These fortified structures, typically circular or square with inward-facing designs, feature thick rammed-earth walls up to 2 meters thick and 20 meters high, housing up to 800 residents from extended clans in self-contained communal villages. Built using local materials like mud, bamboo, timber, and stone, they incorporate defensive elements such as single narrow entrances, slits for surveillance, and internal water sources, reflecting adaptations to the region's turbulent history of raids and isolation. In 2008, UNESCO designated 46 representative tulou as a World Heritage Site, recognizing them as outstanding examples of a building tradition that embodies communal living, defensive organization, and harmony with the subtropical landscape amid rice, tea, and tobacco fields. The Hakka, migrants from northern who settled in during the 12th to 17th centuries to escape conflict and , developed tulou as "little kingdoms" for family clans, promoting equality and . Architecturally, these structures span three to five stories, with ground floors for livestock and storage, upper levels divided into family apartments around central courtyards, and ornate ancestral halls or granaries at the top; roofs are covered in gray tiles with wide eaves for weather protection. Over 20,000 tulou exist across , though many are now preserved as cultural relics amid rural depopulation, serving as symbols of Hakka ingenuity in sustainable, earthquake-resistant construction using techniques. Their inscription under criteria (iii), (iv), and (v) highlights their testimony to cultural traditions, innovative building responses to social needs, and exemplary human-environment interactions.

History and Origins

Hakka Migration and Settlement

The Hakka people, originating from northern China in regions such as Henan and Shanxi, began migrating southward in the 4th century CE during the Jin dynasty (266–420 CE), particularly the fall of the Western Jin amid barbarian invasions (Wu Hu uprising), driven by social unrest, and economic pressures. This initial wave saw early Hakka ancestors fleeing to Jiangxi and other southern areas, marking the beginning of their long history of displacement. Subsequent migrations intensified in the 12th and 13th centuries amid the Song-Jin wars (1127–1234), where Jurchen invasions from the north displaced large populations, compelling the Hakka to seek refuge further south to escape warfare and famine. These movements, often referred to as the third major wave of Hakka migration, solidified their identity as "guest people" (Hakka) among southern Han communities. By the 13th and 14th centuries, Hakka groups arrived in province, particularly settling in the mountainous counties of Yongding and in the southwestern region, where the rugged terrain offered protection from lowland conflicts and banditry. These areas, inland from the coast and spanning over 120 km, allowed the Hakka to establish isolated communities away from threats posed by rival groups and natural hazards like floods. Upon arrival, the Hakka integrated with local indigenous and Min-speaking populations through intermarriage and cultural exchange, adopting some local agricultural practices while maintaining distinct clan-based social structures. This blending helped the Hakka adapt to 's diverse ethnic landscape, though tensions occasionally arose with established Min communities over land and resources. Initially, Hakka settlers constructed simple earthen dwellings suited to the local environment, but by the 15th century, these evolved into communal tulou—fortified, multi-story structures housing entire clans—as a direct response to persistent banditry, inter-clan feuds, and frequent natural disasters in the hilly terrain. The shift to tulou reflected the need for collective defense in a region plagued by instability, with early examples appearing during the late Yuan and early Ming periods. During the Ming dynasty (1368–1644), widespread social unrest, including peasant uprisings and coastal pirate raids, further prompted larger-scale tulou construction to safeguard extended families and livestock from external threats. These developments underscored the tulou's role as both a practical settlement solution and a symbol of Hakka resilience in their new southern homeland.

Construction Periods and Evolution

The construction of originated in the early phase spanning the 13th to 15th centuries, during the transitions between the and Ming dynasties, when small, rectangular prototypes emerged as fortified dwellings. These initial structures drew from northern rammed-earth building traditions, adapted by Hakka settlers to create compact enclosures for clan protection amid regional instability. Typically modest in scale, with square or rectangular floor plans, they emphasized defensive features like thick walls and limited access points, housing smaller family groups in response to immediate security threats. Construction reached its peak from the 16th to 19th centuries, particularly during the , as tulou evolved into larger, more elaborate circular and oval forms to accommodate growing populations and heightened needs for communal defense. This period saw an estimated over 20,000 tulou built across southwestern , with the most sophisticated examples dating to the 17th and 18th centuries, reflecting expanded clan sizes and economic prosperity that enabled multi-story designs housing up to 800 residents each. The shift to circular layouts improved and internal circulation, while ongoing threats from bandits and rival clans drove widespread adoption in rural mountainous areas. In the late phase of the , tulou construction declined sharply after , coinciding with China's modernization and policies that encouraged to cities and reduced the viability of communal rural living. Many structures were abandoned as residents sought better opportunities, leading to deterioration, though selective repairs preserved ; by 2008, approximately 46 exemplary sites were inscribed on the World Heritage List, with around 3,000 tulou still standing overall. Throughout their development, tulou underwent significant evolutionary shifts, transitioning from purely defensive enclosures in early iterations to versatile multi-generational homes that prioritized social cohesion and environmental harmony. Later designs integrated principles for optimal site orientation and layout to promote prosperity and balance, while adaptations like reinforced rammed-earth walls and wooden frameworks addressed the local subtropical , providing natural against humidity and temperature fluctuations. These changes underscored the tulou's role as adaptive architecture, evolving with societal needs while maintaining core communal functions.

Terminology and Classification

Definitions and Etymology

The term tulou (土楼), meaning "earthen building," originates from the dialect spoken in province, where it derives from "tu" (earth) and "lâu" (building or tower), directly reflecting the primary construction material of mixed with other local substances like gravel, bamboo, and wood. These structures represent a unique form of communal fortified residence developed by the in southeastern China's mountainous regions. The broader designation "" was specifically coined for the World Heritage listing in 2008, which encompasses a range of Hakka fortified dwellings, including the iconic roundhouses known as weitou lou (围头楼, or "round-headed buildings") and square variants, all sharing the characteristic earthen walls and defensive layouts built between the 15th and 20th centuries. Fujian tulou are distinct from analogous fortified architectures elsewhere in , such as the diaolou of Guangdong province, which are typically taller, multi-story watchtowers influenced by Western styles and built by returnees for individual or small family defense rather than large communal living. They also differ from Taiwan's ganlan-style houses, which are elevated wooden pile dwellings designed by indigenous groups to protect against flooding and wildlife, lacking the enclosed, fortress-like earthen construction of tulou. Local nomenclature for tulou variations includes terms like "" for oval or boat-shaped forms, as seen in structures such as Wenchang Lou, and "sanhe" referring to three-in-one layouts integrating multiple connected buildings for enhanced communal functionality.

Types and Variations

Fujian tulou exhibit a range of structural types primarily distinguished by their plan shapes, which evolved to meet defensive, communal, and environmental needs of Hakka clans. The most common form is the circular tulou, known as yuanlou (圆楼), which accounts for the majority of surviving examples and exemplifies the mature of these earthen dwellings. These structures typically measure 20 to 70 meters in , with walls up to 2 meters thick, and are capable of housing 80 to 800 residents across multiple stories arranged around a central . The circular design enhances natural ventilation, structural stability, and a sense of communal unity, often featuring concentric rings of rooms for extended families. Prominent examples include the yuanlou in the Tianluokeng cluster, where four circular buildings surround a rectangular one, illustrating clustered arrangements for larger settlements. In contrast, rectangular or square tulou, termed fanglou (方楼), represent an earlier developmental stage, dating primarily to before the widespread adoption of circular forms in the . These are often configured as U-shaped enclosures or fully walled courtyards, better suited to smaller clans due to their more compact scale and simpler construction, typically spanning 30 to 50 meters in length and housing 50 to 300 people. While less prevalent than yuanlou, fanglou prioritize and integration with surrounding landscapes, serving as foundational models from which more complex shapes derived. Their prevalence underscores the adaptive progression of tulou architecture from basic fortified enclosures to elaborate communal fortresses. Beyond these primary types, tulou variations include semi-circular (half-moon), oval, and mixed forms, contributing to roughly five main categories overall: circular (yuanlou), square (fanglou), rectangular, oval, and semi-circular. Semi-circular designs adapt to irregular terrains like hillsides, while oval shapes, such as those in certain Yongding clusters, blend circular efficiency with elongated layouts for better site utilization. Functionally, most tulou serve as residential compounds for multi-generational living, but subtypes include semi-fortified watchtowers with elevated positions and minimal openings for surveillance, reflecting strategic responses to regional threats and topography. These adaptations highlight the versatility of tulou, with over 20,000 still existing across as of the early 21st century (many abandoned or preserved as cultural relics), of which approximately 3,700 are classified or protected.

Architecture and Construction

Materials and Building Techniques

The primary material for Fujian tulou is , known locally as hangtu, composed of locally sourced red clay mixed with sand, slurry, and lime to create a durable binding agent. This mixture is compacted layer by layer to form the outer walls, which can reach up to 2 meters in thickness at the base and support structures 3 to 5 stories high, providing inherent stability. To enhance resilience against earthquakes and typhoons common in the region, the walls incorporate reinforcements such as horizontal strips, wooden frames (often using Chinese fir for load-bearing columns), and stone foundations laid with river pebbles. These elements distribute lateral forces effectively and prevent structural failure during seismic events. The construction process begins with excavating a stone foundation, followed by erecting temporary wooden molds into which the earth mixture is poured and rammed in layers approximately 40 cm high using heavy tampers, allowing each layer to dry before the next is added. This labor-intensive method relies on communal efforts by members. The use of renewable local resources in tulou contributes to its , as the thick earthen walls offer natural , maintaining cooler interiors in summer and warmth in winter against Fujian's variable weather. Over time, techniques have evolved slightly to incorporate more for added strength, though core methods remain tied to traditional practices.

Structural Design and Features

The Fujian tulou are characterized by their robust external design, featuring thick walls that form the primary load-bearing structure, varying from about 0.4 to 2 meters thick, often thicker at the base, to support multi-story heights of up to four or five levels. These walls are constructed using layered techniques with modular blocks reinforced by and wooden elements, topped by drum-tower-style roofs covered in grey tiles with wide overhanging eaves that extend outward for protection against rain and sun. The lower levels incorporate small apertures that gradually widen at higher elevations, optimizing light penetration while maintaining structural integrity. Internally, tulou layouts revolve around a central open —occupying 28 to 46 percent of the total footprint in representative examples—which serves as the communal heart, surrounded by concentric rings of living spaces and corridors. Spiral or shared staircases, often numbering two to four, provide access to upper floors where family quarters are arranged in radial or linear patterns, with ground-level spaces dedicated to storage such as granaries. This organization fosters efficient spatial flow, with wooden frameworks supporting upper levels independent of the earthen walls below. Engineering principles in tulou design emphasize the between earthen walls and wooden superstructures, where circumferential and radial beams distribute loads effectively, enabling spans up to 80 meters in diameter for certain configurations. is achieved through a chimney effect in the central , augmented by skylights and wall slits, which promote natural and temperature regulation via the of the walls. Integration of principles is evident in south-facing entrances that align with environmental harmony, enhancing overall site orientation. Adaptations in tulou contribute to their , with rammed-earth walls demonstrating seismic through flexible timber joints and , allowing many structures to endure over 300 years without collapse despite regional earthquakes. Stone plinths elevate the bases above flood-prone ground, while the earthen composition's low tensile strength is mitigated by layered , ensuring stability in humid subtropical climates.

Social and Cultural Significance

Communal Housing and Equality

The served as multifunctional communal dwellings for extended Hakka clans, housing multiple families in shared spaces that emphasized collective resource management and social cohesion. Each tulou typically accommodated dozens of families, with larger examples supporting up to 80 families and 800 residents across hundreds of rooms, where living units were allocated vertically—often two or three rooms per family per floor—to facilitate self-sufficiency while promoting unity. The uniform size and shape of these rooms underscored egalitarian principles, ensuring no family held spatial privileges and reflecting Hakka values of collectivism and mutual support. Daily life within the tulou revolved around communal facilities that reinforced bonds, including central courtyards featuring ancestral shrines for rituals and gatherings, as well as shared wells, granaries, and areas. Ground-floor spaces often included family-specific kitchens alongside broader communal zones for dining and , allowing residents to pool resources for meals and maintenance. roles, such as overseeing clan decisions or rotations for communal duties, were typically managed collectively through meetings in the ancestral areas, fostering a sense of shared responsibility without fixed hierarchies. The tulou's design embodied Hakka by integrating all members—regardless of or age—into labor and community activities, with women enjoying relatively higher status through practices like equal rights and participation in household production. There were no distinct hierarchical divisions in the layout, such as elevated spaces for elites, which aligned with the clan's emphasis on harmony and collective welfare over individual status. Following the era of agricultural collectivization and subsequent economic reforms, many tulou saw significant depopulation due to urban migration in search of better opportunities, leading to the abandonment of numerous structures that once bustled with hundreds of inhabitants. Today, while most remain underoccupied or repurposed, select tulou continue to house 20 to 50 descendants, preserving elements of traditional communal living amid modern challenges. As of 2025, revitalization projects in areas like Yongding encourage resident returns to sustain cultural traditions.

Defensive and Protective Roles

The were constructed primarily as fortresses to protect Hakka communities from external threats, including bandits, rival , and , in the rugged mountainous regions of southwestern during periods of instability. These structures emerged in the amid the Ming-Qing dynastic transition, when sporadic bandit attacks plagued newly settled areas, prompting alliances of lineages to build communal defenses like Ji’an Lou (ca. 1600–1643) under elite supervision. The thick rammed-earth walls, often 1 to 2 meters wide and up to five stories high, were engineered to resist gunfire, sieges, and physical assaults, with narrow single entrances reinforced by heavy wooden doors sometimes clad in iron plating. Small windows positioned only above the first floor minimized vulnerabilities, while gun ports at the upper levels allowed residents to defend against intruders without exposing themselves. Defensive elements integrated into tulou design enhanced their fortress-like capabilities, including central courtyards for coordinated and, in select cases, surrounding ditches that served dual drainage and barrier functions. Historical accounts document their role in withstanding threats during the Qing era, such as localized rebellions and bandit raids, where the collective organization of up to 800 inhabitants per structure proved effective in repelling attacks through solidarity and strategic positioning. Although specific armories were not universally featured, lower levels often included storage spaces that could accommodate weapons and supplies for prolonged defense. Beyond human threats, tulou provided robust , with elevated foundations and sloping roofs designed to resist flooding common in the region's year-round rainfall, channeling water via away from the structure. The rammed-earth walls, compacted with additives like and egg whites, offered inherent fireproofing and thermal stability, safeguarding wooden upper floors from both accidental blazes and during conflicts. These features ensured against typhoons, earthquakes, and , contributing to the of many tulou over centuries. Over time, tulou design evolved from highly militarized forms in the early Qing period, emphasizing active fortifications against immediate dangers, to later variants that prioritized passive through remote in mountainous terrain, reducing exposure to threats as regional stability improved. By the 19th and 20th centuries, with declining , the focus shifted toward communal living while retaining core protective attributes.

Notable Examples

Prominent Clusters

The Tianluokeng Tulou cluster, located in Shuyang Township of Nanjing County, comprises four round tulou surrounding a central square one, poetically dubbed "Four Dishes and One Soup" for their arrangement. The round structures—Zhenchang Lou, Ruiyun Lou, Hechang Lou, and Wenchang Lou—were constructed between 1912 and 1966 by successive generations of the Huang family, illustrating the adaptive growth of a single lineage from a modest square dwelling built in 1796 to a fortified ensemble that housed up to 300 residents. This cluster exemplifies the progression of Hakka communal architecture, with walls up to 2 meters thick providing defense while internal layouts evolved to accommodate expanding family needs. The Chuxi Tulou cluster in Xiayang Town, Yongding County, stands as one of the densest concentrations of these earthen edifices, featuring over 30 structures dating from the 15th to the 20th centuries and blending round, square, and rectangular forms. Among them, Jiqing Lou, erected in 1419 during the , represents one of the earliest known circular tulou, with its design enclosing approximately 212 rooms across four stories for 600-700 inhabitants. The cluster's varied morphologies highlight the versatility of rammed-earth techniques in response to terrain and clan size, fostering self-sufficient villages that integrated and . In Hukeng Town of Yongding County, the Nanxi Tulou cluster extends along a 10-kilometer , encompassing over 100 buildings harmoniously nestled amid terraced fields and waterways, earning it the moniker "Tulou Great Wall." Yanxiang Lou, a prominent round tulou built in the during the , exemplifies this integration with its four-story height, 136 rooms, and strategic placement that leverages natural barriers for protection. The site's linear arrangement along the Nanxi stream underscores how Hakka settlers adapted building practices to linear settlement patterns, supporting larger populations through shared resources. These clusters collectively embody the historical and architectural essence of , including a significant portion of the 46 structures inscribed on the World Heritage List in 2008 (such as 5 from Tianluokeng, 10 from Chuxi, and a few from Nanxi), and vividly demonstrate the communal expansion of Hakka society from isolated fortresses to interconnected villages over centuries. Their preservation highlights the enduring legacy of earthen construction in promoting social cohesion and environmental adaptation in mountainous regions.

Iconic Individual Tulou

Chengqi Lou, situated in Yongding County and constructed in 1703, stands as the largest square tulou in , measuring 62 meters by 51 meters and capable of housing more than 600 residents across its multi-ring structure. Nicknamed the "King of Earth Buildings" for its monumental scale and communal design, it exemplifies the Hakka people's emphasis on collective living and defense within a single, fortified enclosure. Yuchang Lou in County, dating back to 1308, is recognized as the oldest surviving tulou, featuring a distinctive five-story design that has tilted over time—earning it the moniker "dancing building" due to in the underlying . This lean does not compromise its structural integrity, showcasing the resilience of rammed-earth construction against natural shifts. Its endurance through centuries highlights the longevity of tulou architecture in Fujian's rugged terrain. Zhencheng Lou, completed in 1912 in Yongding County and also known as the "Prince of Tulou," captivates with its ornate interior boasting 72 rooms adorned in traditional motifs, while incorporating subtle modern elements like improved ventilation in its dual-ring layout. This building represents a transitional phase in tulou evolution, merging age-old Hakka aesthetics with early 20th-century innovations for enhanced habitability. Fujian tulou exhibit remarkable variation in scale, with Hegui Lou as a prominent rectangular example designed to shelter large extended families in a fortress-like form. In contrast, Ruiyun Lou (also known as Huiyun Lou) is among the smaller known, with a 35-meter , illustrating how tulou adapted to available resources and sizes while maintaining core defensive principles. These extremes underscore the versatility of tulou as both monumental communal hubs and compact family strongholds.

As the first inscribed example of traditional Chinese earthen architecture on the World Heritage List, the highlight the global significance of rammed-earth construction techniques, which had previously been underrepresented among China's heritage sites dominated by stone, wood, and brick structures. Since the inscription, the UNESCO status has elevated international awareness of the tulou, attracting funding from global organizations and spurring academic research into their preservation. By 2025, this recognition has facilitated initiatives such as projects funded by international foundations, including efforts to integrate modern practices while maintaining structural integrity. These developments have enhanced cross-disciplinary investigations into the tulou's architectural and cultural value.

Conservation Challenges and Efforts

The conservation of Fujian tulou faces significant threats from and rural depopulation, which have led to the abandonment of many structures since the mid-20th century, with thousands now in disrepair or lost entirely due to neglect. Material decay is a primary concern, as the walls are susceptible to from and lack of maintenance, while roof collapses affect many surveyed tulou. Seismic risks further exacerbate vulnerabilities, given the earthen construction's response to loads, though many tulou have historically withstood moderate tremors. , while economically beneficial, contributes to wear through increased foot traffic and unauthorized modifications, such as added windows and doors that compromise structural integrity. In response, the Chinese government implemented the "Management Measures of Fujian Province for the Protection of Cultural Heritages of " in 2006, establishing legal frameworks and county-level management offices in Yongding, , and Hua'an to oversee protection and enforcement. provides ongoing monitoring through periodic reports and state-of-conservation assessments, emphasizing the need for defined indicators to track threats like impacts on structural safety. Local repair efforts prioritize traditional techniques, such as grouting and stitching cracks with earthen mortar to restore walls while preserving authenticity. Recent initiatives as of 2025 incorporate digital technologies for enhanced preservation, including AI-based models like YOLOv8 for automated detection of wooden structure damages such as cracks and holes, enabling real-time monitoring and early interventions across tulou clusters. Eco-tourism funding supports projects, such as the Foundation-backed revitalization of seven tulou sites, transforming them into community spaces like food kiosks and cultural centers to boost occupancy and sustainability. Community involvement is central, with Hakka descendants participating in and training for maintenance, as seen in restorations like Taoshu Lou, where local funding and resident input balance traditional methods with modern needs.

Sustainable practices, including managing visitor density at heritage sites, are implemented to protect the UNESCO-listed tulou from overcrowding.

Cultural Influence

Representation in Media

Fujian tulou have been prominently featured in cinema, often symbolizing communal strength and ancient Chinese heritage. In Disney's live-action adaptation of Mulan (2020), the titular character's family home is depicted as a tulou, showcasing the structures' circular, fortified design in key opening scenes to evoke rural isolation and familial bonds. This portrayal, though not historically precise for the legendary setting, drew global attention to the tulou's architectural uniqueness following the film's release. Similarly, the 2016 animated fantasy film Big Fish & Begonia incorporated real photographs of tulou from Fujian and Guangdong provinces, redrawing them as ethereal backdrops to represent otherworldly communal realms. Documentaries have further highlighted tulou in educational media. The 2010 NHK production Giant Community House: Fujian Tulou, part of UNESCO's World Heritage series, explores the buildings' construction and cultural significance through on-site footage, emphasizing their role in Hakka defensive living. More recently, CGTN's 2025 live stream Discover Fujian Tulou – Inspiration Behind Mulan's Hometown revisited the sites, blending tourism promotion with historical narration to illustrate their enduring appeal. In , tulou appear in works examining Hakka traditions and rural . Modern authors, including Hanmin Huang in Fujian's Tulou: A of Chinese Traditional Civilian Residence (2019), provide detailed ethnographic accounts, portraying tulou as living archives of social harmony and . Tulou have also been celebrated in and popular . issued a set of stamps in 2021 featuring iconic tulou clusters like Yongding's, commemorating their status and promoting cultural preservation. National Geographic's 2018 feature " " included vivid photography and narratives on their defensive origins, reaching millions through print and online platforms. The 2020s tourism surge, amplified by Mulan's release, led to viral content on platforms like and , where users shared immersive videos of tulou interiors, garnering widespread shares for their "fairytale" aesthetic. Symbolically, tulou representations in often embody against adversity and harmonious communal living, as seen in UNESCO-aligned documentaries that frame them as emblems of Hakka ingenuity in China's southeastern mountains. These depictions underscore themes of collective defense and cultural continuity, briefly echoing broader communal housing ideals without delving into daily social structures.

Modern Legacy and Adaptations

In the 2020s, Fujian tulou have inspired contemporary architectural practices emphasizing , particularly through the revival of rammed-earth construction techniques in eco-friendly buildings across and beyond. The rammed-earth method, central to tulou design, offers natural thermal regulation and low environmental impact, influencing green projects such as the initiatives in Shi, where traditional structures are retrofitted with modern insulation while preserving earthen walls. This approach has been adopted in broader Chinese sustainable developments, including rural revitalization programs that integrate tulou-inspired communal layouts to promote energy-efficient, community-oriented housing. Globally, architects have drawn from tulou's circular forms and defensive resilience in designing resilient eco-structures, as seen in exhibitions highlighting earthen at forums on sustainable building. Cultural revival efforts have sustained Hakka traditions within tulou sites, fostering through festivals and educational initiatives. Annual Hakka cultural festivals, including song performances and traditional ceremonies, are held in tulou clusters to celebrate communal and attract younger generations to ancestral practices. Educational programs, such as rammed-earth workshops conducted inside restored tulou, teach sustainable building techniques and Hakka history, contributing to rural cultural continuity. As of 2025, a small number of tulou remain inhabited by local Hakka families, primarily elderly residents, supported by preservation efforts that enable ongoing habitation and cultural transmission. However, urbanization has led to the abandonment of many tulou, transforming them primarily into cultural and tourist sites while efforts continue to encourage in remaining inhabited ones. Modern adaptations have transformed select tulou into multifunctional spaces, including museums and research facilities, while incorporating for long-term viability. The Tulou Museum, housed within a historic structure in Yongding County, serves as an educational hub displaying artifacts and architectural models to document Hakka ingenuity. Some tulou have been repurposed as boutique hotels and cultural centers, blending original earthen aesthetics with contemporary amenities to support economic sustainability without altering core designs. The Research Institute conducts studies on structural integrity and heritage management, utilizing these sites for applied research. Integration of , such as AI-driven platforms, enables of structural health through sensors in walls, aiding preventive in inhabited tulou. The global legacy of tulou extends through UNESCO initiatives and Hakka diaspora communities, which actively preserve and reinterpret these traditions. UNESCO exhibits, including digital displays at world heritage centers, showcase tulou as exemplars of communal , inspiring adaptive models in other earthen heritage sites worldwide. In diaspora communities, such as those in and , Hakka groups organize events like the annual Yimin Festival to honor tulou-inspired communal values, incorporating virtual tours and cultural exchanges to maintain ties to origins. These efforts ensure tulou's principles of and social cohesion influence contemporary multicultural practices.
