Among them, the students were: Huang Gongwang, Yu Ji, Guo Wei, Liu Guan, Qian Liangyou, Zhu Derun, Ke Jiusi, Jiexisi, Kangli Zishan, Zhang Yu, Yu He, etc.; students of the student generation, such as: Kangli Zishan's disciples Rao Jie and Wei Su, etc.; relatives The descendants include: younger brother Zhao Mengyu, wife Duan Sheng, son Zhao Yong, nephew Wang Meng, etc. Among these people, Yu Ji, Kang Lizishan, Zhang Yu, etc. were not restricted by teachers, but developed their own styles, and their achievements in the calligraphy world in the middle and late Yuan Dynasty were more significant.
