Introduction to Dangar Office: Danggar Office is located opposite Yanji Trading Company. During the Daoguang period, because Huangyuan Haizang was a major hub for trade between China and foreign countries, the Dangar Hall was specially set up, which belonged to Xining Prefecture. Now after restoration, there are lobby, six rooms, meeting hall and other buildings. Every day in the department, local folk artists perform regular county government performances, truly recreating the office and life scenes at that time.
