"Ancestors lived in Yongchang, Gong County, the capital of song dynasty, Henan Province, and later moved to Quzhou, where the Xu family got married in Lanxi, hence the name Yongchang. It is said that its land will last forever and its descendants will prosper forever. " Zhao Xianzuo, a Zhao native of Yongchang in the Wanli period of the Ming Dynasty, recorded the origin of Yongchang's name in Yongchang Ji. Yongchang Village was originally formed after Zhao Gongchuan, the seventh descendant of Song Taizu's brother Zhao Tingmei, moved in. During the Ming and Qing Dynasties, due to the convenient land and water transportation, it became one of the most important markets in Gulanxi County, where a large number of Huizhou merchants gathered and a guild hall was built.
