Green shade pavilion introduction: There was an ancient maple on the west side of the building. The small pavilion was shrouded in the shade of the tree. According to the sunflower poem written by Gao Qi: "In the bright red light, the clusters are beside the green shade." Hence the name. The building is like a pavilion, built on a hard hill and close to the water. It was already there when Liu's Han Bizhuang was built. There is a stone plaque embedded on the wall of Xuannan courtyard, with Qian Daxin writing "Huabu Xiaozhu".
