Wuchuan Town (now the west of Wuchuan County, Inner Mongolia) is one of the six major military towns in China's history that were flexibly defended during the Northern Dynasties. Formerly known as Black City, it was later changed to Wuchuan. In the first year of Wutai (528), the ghost town was changed to SHEN WOO County, which belonged to Shuozhou. Wuchuan town was a frontier stronghold at that time, and a large number of generals and troops gathered. After the Six Towns Rebellion, many soldiers in Wuchuan Town became pivotal figures. For example, Yu Wentai, the founder of the Northern Zhou Dynasty, was the leader of Wuchuan team, and Yang Zhong, the father of Emperor Wen of Sui, the Emperor of Sui Dynasty, and his father and ancestors were soldiers of Wuchuan. In the Tang Dynasty, Li's ancestors were also considered to be soldiers from Wuchuan Town.
