The calligraphy of Fei Cai Dang Drama Post, He Shi Post and Cheng Tu Post is thin and hard, and the strokes are penetrating the back of the paper, and they are placed sideways and vertically, changing their posture; However, Bochong Post, Poem of Worshiping Zhong Yue's Life, and Poem of Danmo Qiushan are full of sinews and bones, turning fat and beautiful, and emerging in many ways; "Escape from the Summer", "Year's Eve" and "Going out to the Customs by the Hou" are different in attitude.
