Introduction to the Flower Hall of Xiaohuanglou: It is a double-story pavilion with three rooms in width and five columns in depth, with a bucket-style wooden frame; dragons and phoenixes are depicted on the beams, and the doors and windows are all made of nanmu. They are exquisite in workmanship and exquisitely carved. There are overhanging balconies on both sides of the upstairs corridor, connected to the rockery. Against the walls on both sides of the building are snow caves made of glutinous rice and Sanhe soil, which are still well protected.
