Traces of ancient homes discovered in Sichuan

Archaeologists have discovered more than 3,500 ancient post holes on the Anning River Plain in Sichuan province.

The holes were made to hold posts for the construction of shelters more than 1,800 years before the establishment of the Qin Dynasty (221-206 BC), China's first feudal dynasty.

The holes were found in 2014 after archaeologists began the excavation to ensure no cultural relics were damaged in the building of the Emei-Miyi section of the high-speed Chengdu-Kunming railway line linking Sichuan and neighboring Yunnan province, said Song Ming, an information officer with the Liangshan Yi autonomous prefecture government.
