2. Zhang Zhi (? -about 192), the word Boying, from Jiuquan, Dunhuang (now Gansu). Noble personality, unwilling to be an official. His cursive script is superb, and he is the founder of modern grass, known as "the sage of grass" in history. His achievements in calligraphy art are hard-won. His clothes and silk must be studied before practice. He is studying in the pool. The water in the pool is black. Liang Daiyu said in Shupin: "Zhang (ambition) is the work, followed by sex."

3. Cai Yong (132-192) was born in (now south of Qixian County, Henan Province), so later generations also called him "Cai Zhonglang". In Cai Yong, seal script is the most successful and prestigious. Therefore, later generations often attribute some famous historical sites in the Eastern Han Dynasty to this place, such as Huashan, Guotai, Xiacheng and Lujun. For him, some people even described the three-body stone knot in Wei Dynasty as his handwriting. In the fourth year of Xiping, he asked Zhengding Six Classics, and Emperor Ling approved his suggestion. He personally wrote "Eight Points" (Han Li) on the tablet for workers to engrave and stand outside the business school. Since the monument was erected, more than 1000 cars have crowded the streets every day. This stone tablet is called Hongdu Shijing, also called Xiping Shijing. Emperor Ling ordered the workers to repair Hongdumen. Cai Yong was inspired when he saw the workers painting the walls with chalk, so he created a flying white paper.
