The ancient cultural features of the pre-Qin period in Northern Jiangsu have become an important topic in Jiangsu archaeology. It is necessary to carry out large-scale archaeological investigation. There are two reasons.

Firstly, shunshanji culture has been recognized by academic circles after the excavation of Shunshanji site in Sihong, which will certainly promote the exploration of ancient culture in Huaihe River Basin and Huanghuai River Basin. Yishusi belongs to the Huaihe River Basin, which lies in the middle of Haidai district cultural sequence and Huaihe River Basin cultural sequence in the lower Yellow River.

Secondly, in the past ten years of the 21st century, salt archaeology has made great progress and solved very important academic issues. Especially in the Yin Ruins period of the Shang Dynasty, the only thing that the Shang Dynasty had to do was to strengthen the control of the East and obtain the salt industry resources.

Since 2013, the cooperation between Nanjing Museum and the National Museum has begun to carry out a regional systematic investigation in Sihong area. In this case, the conditions for our archaeological investigation in Xuzhou area have been mature. Therefore, since 2014, the archaeology Department has successively carried out the systematic archaeological survey in this region.
