During my long artistic creation, I met a group of friends who approved documents. The seal used is carefully carved by my good friend Ye Dagen, and the seal cutting technique is skillful. Many friends asked Li to write an inscription for himself. Hunan painter Peng is good at painting all kinds of birds and beasts and has a deep friendship with him. Many tigers and lions were invited to write poems. Guan Shanyue, a good friend, also kept close contact and exchanged experiences. Mr. Xue Shuangjia, a good friend in the same city, often participates in various activities with him. Jiangyin Zhongshan Park often holds calligraphy exchange meetings and often writes and draws on the ground. Li Fengxiang, the eldest son of Li Yin, inherited his family studies and won the second and third prizes in the calligraphy competition for three consecutive years. At the age of 25, he became a member of Jiangyin Calligraphy Association, and his works include Roaming in the Old Country. Starting from 1993, Li Yin began to take classes and accept apprentices. Many painting and calligraphy students are very famous, and students come to visit with artistic dreams. Li Yin gave them a detailed explanation and demonstration. The students carefully draw and write in class, finish the homework assigned by Li Yin when they get home, and take it home for him to check next time. If they feel imperfect, point it out and teach them how to improve. Later, the students made proud achievements in various competitions with the skills they learned at school, adding luster to themselves. I have taught more than 30 students. Some of the students I taught were admitted to the Central Academy of Fine Arts, some went abroad for further study, and some became art teachers.
