The strongest anchor
706 CE, not 685.
Prince Zhanghuai died in 684, but his Qianling tomb and mural programme belong to his state reburial in 706. That distinction corrects one of the internet’s most repeated errors.
The hunting-procession mural includes mounted hunters, falcons and hounds. Its date is secure. Calling every depicted hound a modern Xigou would go beyond the evidence, but the scene is excellent evidence that specialised hunting dogs were embedded in elite Tang material culture in the region now associated with the Shaanxi Xigou.

Resemblance is evidence for a tradition. It is not proof of an unbroken breed.
Selected chronology
A timeline with the gaps left visible.
Tang tomb mural programme
The tomb of Prince Zhanghuai is constructed for his reburial at Qianling. Its hunting scene includes hounds in an elite expedition.
Qing court sighthound portraiture
Giuseppe Castiglione’s dog paintings record named, prized Chinese greyhound-like hounds at the Qianlong court.
A documentary field photograph
A Japanese survey photograph labels slender Mongolian hunting dogs as xigou, offering visual evidence of a regional working type.
Modern conservation enters the ring
CKU conservation activity includes appraisal, registration and a dedicated Shaanxi Xigou show in Xianyang.
Genomic evidence sharpens the picture
A peer-reviewed study reports marked differences between sampled Shaanxi and Shandong Thin dog populations.
Origins
The Silk Road is context, not a conclusion.
The feathered Shaanxi type invites comparison with the Saluki and Central Asian Tazy. Geography makes contact plausible; morphology makes the question compelling. Neither tells us which way genes moved.
Older writing often proposes a single migration story: Near Eastern hounds travelled east, or Chinese hounds travelled west. Modern sighthound genomics suggests multiple origins and strong geographic structure. The responsible position is therefore narrower: Chinese sighthounds belong inside the history of Eurasian exchange, but the exact relationship among the regional landraces requires denser sampling and ancient DNA.

Research agenda
What we still need to know.
Can specific historical images be securely identified?
Most labels were applied by modern authors. We need iconographic work that distinguishes a generic hunting hound from a regional Xigou claim.
What survives in village populations?
Modern standards and show dogs record only part of a landrace. Field documentation should include working owners, local vocabulary and geographic provenance.
How much recent introgression has occurred?
Oral histories commonly report Greyhound and Whippet influence. Genomic sampling could clarify when and where that occurred.
