Сыку цюаньшу
The existing hall which is patterned on the Tianyi Ge in Ningbo was rebuilt behind the Wenhua Palace, in the reign of the Qianlong Emperor. Completed in 1776, it was a kind of library and stored numerous works, including a copy of the "Siku Quanshu". The Wenjin Ge in the Chengde Mountain Resort is its counterpart.
