Former Lu Tusi Yamen, Historical government complex in Yongdeng County, China.

The Former Lu Tusi Yamen stands in Liancheng Village, Liancheng Town, Yongdeng County, Gansu. First built in 1378 (11th year of Hongwu), it faces south and is a brick-and-timber complex; with its official garden and Miaoyin Temple it covers nearly 40,000 square metres, of which 2,877 square metres are Ming-era buildings. The protected site also takes in Xianjiao Temple and the Leitan altar.

The yamen was first built in 1378, the eleventh year of the Ming Hongwu era, and was expanded and rebuilt repeatedly in later periods. Its founder, Tuo Huan, a Yuan imperial descendant and Prince of Anding, surrendered to the Ming and was settled at Liancheng as a tusi. His grandson She Jia received the surname Lu from Emperor Chengzu and was renamed Lu Xian. The line passed through nineteen generations until the tusi system was abolished in 1931.

The Lu surname came from Emperor Chengzu of the Ming, who granted it to the third tusi, She Jia, renaming him Lu Xian; the family held the post for nineteen generations until the tusi system was abolished in 1931. The west side of the complex holds Miaoyin Temple, founded in 1427 as Datong Temple and renamed in the Guangxu era. The protected site also takes in Xianjiao Temple and the Leitan altar.

The protected site takes in four separate components: the yamen itself, the Miaoyin Temple on its west side, the Xianjiao Temple and the Leitan altar. The yamen faces south and is built of brick and timber, so allow time to walk between the temple and the other buildings rather than expecting one courtyard.

The Lu line began with Tuo Huan, a descendant of Kublai's son Köligen, who held the title Prince of Anding and the post of Zhongshu Canzhi Zhengshi under the Yuan. He surrendered with his troops in the early Ming and was settled at Liancheng as a tusi. His grandson She Jia received the surname Lu from the Yongle emperor and was renamed Lu Xian.
