Le récit

Comprendre la culture Cenxun Cave: Sui–Tang Southern Lineages

Archaeogenetic results from three individuals (440–658 CE) excavated at Cenxun Cave, Pingguo County, Guangxi. mtDNA haplogroups: M (2) and M10 (1). Limited samples suggest maternal links to southern East Asian populations amid Sui–Tang political changes.

Chronologie

Moments clés de l'histoire de cette culture

440 CE

Earliest dated individual from Cenxun

One of the Cenxun Cave samples dates to c. 440 CE, situating it in the late Northern and Southern period.

581 CE

Sui dynasty unification begins

The Sui dynasty unifies much of China (581 CE), increasing administrative links to southern regions like Guangxi.

618 CE

Tang dynasty founded

The Tang dynasty (from 618 CE) expands cultural and economic networks that touch southern China.

658 CE

Latest dated individual from Cenxun

The most recent Cenxun sample dates to c. 658 CE, in the early Tang era.

Origins & Emergence

Cenxun Cave sits in the rolling karst of Pingguo County, Baise City, Guangxi — a landscape of limestone cliffs and rice terraces that has shaped human lives for millennia. The burials and remains dated between 440 CE and 658 CE place these individuals in a fluid historical window: the late Northern and Southern era, the Sui unification (581–618 CE), and the early Tang expansion (from 618 CE onward). Archaeological data indicates local practices that likely blend long-standing southern lifeways with increasing connections to imperial networks during the Sui–Tang transformation.

Limited material evidence recovered at the cave (contextualized burials rather than rich grave goods) suggests these were local agrarian communities rather than elite migration cohorts. Regional ceramic types and landscape use imply continuity of southern cultural practices. Because only three individuals were sampled, conclusions about population origins remain provisional. However, the genetic signal combined with the archaeological context paints a cinematic picture: small-scale farming communities nested in rugged karst valleys, negotiating new political horizons as northern dynastic powers consolidated control over southern reaches.

  • Site: Cenxun Cave, Taiping Town, Pingguo County, Baise City, Guangxi
  • Date range places remains across late 5th to mid-7th centuries CE
  • Archaeological evidence indicates local southern communities with growing ties to Sui–Tang polities

Daily Life & Society

The human story in Guangxi during the Sui–Tang era is one of rhythm and adaptation. Wet-rice cultivation dominated lowland valleys and terraced slopes; people shaped waterways, tended paddy cycles, and raised domesticated plants that anchored village life. Material traces from coastal and inland southern China show household craft, simple metal tools, and local ceramic traditions — a mosaic of everyday items rather than conspicuous elite display in places like Cenxun Cave.

Burial practices in karst caves often emphasize community use of sheltered rock spaces and may reflect local ritual landscapes rather than courtly funerary systems. Archaeological data indicates modest grave contexts at Cenxun, which could signal family- or village-level burial customs. Ethnic and linguistic diversity probably characterized the region: Tai-Kadai, Hmong-Mien, and other southern groups are part of the broader ethnographic picture, but the archaeological record alone cannot assign language or identity. As imperial reach stretched south under the Sui and Tang, markets and administrative ties increased, bringing new goods and ideas — yet daily life likely remained largely anchored in long-established local subsistence and social networks.

  • Economy centered on wet-rice agriculture and local crafts
  • Burial evidence suggests community-level ritual use of caves rather than elite tombs

Genetic Profile

Three individuals from Cenxun Cave were successfully typed for mitochondrial DNA. The maternal lineages observed are within haplogroup M: two samples assigned to broad M and one to subclade M10. Haplogroup M is an ancient maternal lineage widespread across East Asia and into South and Southeast Asia; its presence here is consistent with long-standing southern-East Asian maternal ancestry in Guangxi.

M10 is a lineage found at low to moderate frequencies in parts of East Asia and often appears in ancient and modern southern Chinese and neighboring populations. These mtDNA results tentatively indicate maternal continuity with southern East Asian gene pools during the Sui–Tang transition. Crucially, no reliable Y‑DNA haplogroup data were reported for these three samples, and the small sample size (n = 3) makes any population-level inference preliminary. Archaeogenetics here functions best as a hint: the maternal signal aligns with archaeological expectations of local southern ancestry, but broader conclusions—about admixture, migration, or demographic shifts—require many more samples and genome-wide data.

Researchers should treat these findings as an initial window: informative but limited in scope.

  • mtDNA: M (2), M10 (1) — consistent with southern East Asian maternal lineages
  • Y-DNA: not reported; small sample size (n=3) means conclusions are preliminary

Legacy & Modern Connections

The Cenxun Cave individuals belong to a deep southern genetic and cultural current that flows into the present. Modern populations of Guangxi are genetically diverse, reflecting millennia of local continuity, internal migrations, and interactions with neighboring regions. The mtDNA M signals from Cenxun dovetail with broader patterns seen across southern China and Southeast Asia, where maternal lineages often retain ancient regional signatures even as autosomal genomes show layers of interaction.

Archaeologically and genetically, the Sui–Tang centuries were a period of integration rather than wholesale replacement in many southern locales. For museum audiences and modern descendants, Cenxun Cave offers a tangible link to lives lived in rice valleys and karst shadowlands, a reminder that political change unfolded across landscapes already inhabited by resilient local communities. Future sampling and genome-wide analyses will clarify the depth of continuity and the pathways of exchange that shaped Guangxi's human tapestry.

  • mtDNA continuity suggests links between ancient Cenxun individuals and regional southern populations
  • Broader population history requires more samples and genome-wide data to resolve admixture and migration
