Introduction to Yinglianyuan: Yinglianyuan is located next to Yufeng Building. It is a ballroom where Hu Xueyan entertains foreign guests and dances. There are two very large floor-to-ceiling mirrors in the hall, which were given by the British envoy at that time; the large and crystal-clear colorful chandelier on the top of the pavilion was also given to Hu Xueyan by a Japanese friend.
