Lijuan Building is located in the west of the First People's Hospital, Chengzhong Road, Duanzhou District. This is the entrance of Zhaoqing Mansion, built in 1118. The ancient Duanzhou was once the seal of Zhao Yu, the Hui Zong of Song. After Zhao Yu's succession, Zhao Yu gave the book to the place as "Zhaoqing Mansion". The local guard built a high platform in front of the mansion to build this building for the use of this imperial book, so this building is also called "Yushu Building."
