Lutusi Yamen is a relatively well-preserved palace-style ancient building group among the Tusi relic buildings at the border of Gansu. It sits on the bank of Datong River and consists of three parts: Lutusi Yamen, Miaoyin Temple, and Tusi Garden. Lutusi Yamen was the place where Lu Tusi worked and lived, along with his family. It was built during the 11th year of Ming Emperor Hongwu's reign (1378). The Yamen is near mountains and river. It sits in the north while facing the south. Inside, there are several buildings with significant folk atmosphere.
