According to the data, "Jiangkou Shen Yin Site" is located in Minjiang River, Jiangkou Town, Pengshan District, Meishan City, Sichuan Province. In 20 10, it was announced as a cultural relics protection unit at Meishan level, with a distribution area of 1 10,000 square meters. Since the Qing Dynasty, many documents have recorded that Zhang Zeng, the commander-in-chief of the western regions in the late Ming Dynasty, had sunk silver here.

"Shu Bi" records: "(Zhang) Xian (Yang) was afraid of the general trend and led tens of thousands of troops with 10, carrying thousands of gold treasures down the river to fight for its exhibition." According to legend, in 1646, the Qing army entered Sichuan, and Zhang led the army to break through western Sichuan with thousands of ships of gold and silver. However, during the transfer, the landlord's armed forces were defeated in Zhang's treasure fleet, and thousands of ships of gold and silver sank to the bottom of the river. Zhang only brought a few pro-armies to break through successfully.

There are more details about Shen Yin in the documentary in southern Sichuan: "When Zhang's troops left Sichuan by water, there were too many silver coins to be carried by wooden boats, so Zhang ordered craftsmen to make many wooden clips, put silver ingots in them and let them drift down, intending to salvage them in a narrow river. But then the troops were blocked and the river boat blocked the river, so most of the silver sank into the river. " In other words, Zhang went south from Chengdu with thousands of ships of gold, silver and jewelry, and was raided by bureaucrats in western Sichuan in Jiangkou Town, Pengshan District, Meishan City. Most ships loaded with gold, silver and jewels sank into the river.

It is reported that a new round of excavation will be carried out from June 20 17 to June 201,and it is expected that the focus of excavation may be to find the wooden sunken ship in the battle of Jiangkou. At present, preliminary planning and planning have been carried out.
