Introduction to Sansui Hall: Sansui Hall is located at the main entrance of Yuyuan Garden and was built in the 25th year of Qianlong’s reign in the Qing Dynasty (1760). It was originally the Leshou Hall. It was expropriated as the office of Shanghai County Government in the early Qing Dynasty. When the West Garden was rebuilt, it was rebuilt as the Sansui Hall. The lotus pond in the south of Sansui Hall, Fuyi Pavilion, Green Wave Corridor, Haolefang, Hexian Pavilion, Qingfen Hall, Ninghui Pavilion, etc. have become scenic spots outside Yu Garden.
