Introduction to the Four-sided Hall: The Four-sided Hall is a Ming Dynasty building. It was originally the place where the famous calligrapher and calligrapher Dong Qichang, the Minister of Rites and the Wanli Period of the Ming Dynasty, sang freely. It is also known as the "Zhujia Mountain House" (also known as the East Garden). Dong Gong once wrote for this hall. The screen is "the hall is open on all sides, with a pool in front and a stone on the back. The pavilion is open and clear. There is a wide courtyard in front, with Qi Ke and Cong Xiao, reflecting the belt on the left and right. I washed my feet when I came to the world, and I hope that I will shake my tassel on the right." In front of the hall, there are more than 300 ancient camphors. In the year of 2016, the sun was shaded and full of vitality. The ancient vines were coiled behind the hall, giving it a simple style.
