The terminal station of the small train is called Tuanshan Village. The winding old bluestone slabs connect the old houses together and string together a period of dusty history. Most of the people in Tuanshan Village are surnamed Zhang. It is said that they migrated from Jiangxi. They started mining here and entered the business community, earning a huge Zhangjia Garden. The glory of Zhang Jiahuang has ceased to exist yesterday, leaving only the embarrassment of the years.
