Where is the earliest place in China?

Seven maps were unearthed from Qin Tomb in Fangmatan, Tianshui, Gansu Province, and the mapping date was determined. Experts confirmed that these maps are the earliest physical maps in China. These seven maps were discovered by Gansu Provincial Institute of Cultural Relics and Archaeology at 1986. Researcher He Shuangquan confirmed by textual research that the drawing date was the eighth year of Qin Shihuang (239 BC). According to the research of the State Bureau of Surveying and Mapping, they are more than 300 years earlier than the Huahe map in Anbeilin 1300, and about 300 years earlier than the map of the Western Han Dynasty 1973 unearthed in Mawangdui, Changsha, Hunan. Author unknown. He Shuangquan said that these maps were drawn with black lines on four pine boards with basically the same size, and the graphics were clear and complete. This map reflects the administrative region, geographical profile and economic profile of Qin during the Warring States Period. There are as many as 82 notes on place names, rivers, mountains and forest resources in the map. Surprisingly, on today's chessboard map, the tributaries of the Weishui River and many canyons in this area can still be found, which is consistent with the record in the book "Notes on Water Classics". Archaeologists and historical experts believe that these wooden maps of the Qin Dynasty provide physical evidence for the study of China. The United States developed map literature in the pre-Qin period, which promoted the development of China history. This is an important part of the map of China for hundreds of years, and it is a surveying and mapping technology to study the precious data of China.
