Several 1700- year-old Han style tombs were unearthed in Kuqa County of the Xinjiang Uygur Autonomous Region at a construction site of an underground business street. This is the first time Han style tombs at that age have been found in Xinjiang.
 
Comparing with tombs discovered in Jiangsu, Shandong, Shaanxi, Henan and Shanxi provinces, these tombs were identified as being built during the Qiuci Kingdom, between the middle of 3rd century and 4th century.

The discovery of these tombs fills a gaping hole concerning the ancient Qiuci Kingdom. They are significant for researching intimate political, commercial and cultural relationships between the Xiyu (western regions) Areas, the ancient Xinjiang region, and central China.
