I have practiced all of these: Jin Dynasty calligraphy had a great influence on later generations, and it had a strong official meaning. In fact, both Yan Zhenqing and Mi Fu were influenced by Wang Xizhi in their early stages. However, they later developed their own styles, among which Wang Xianzhi was a representative figure. Moreover, Mi Fu's style was formed on the basis of Wang Xianzhi. I personally like their styles better - they have individual personalities. Haha, you can practice them together. In fact, the foundation of soft-pen calligraphy can determine the style of hard-pen calligraphy. You may not be able to see results in a short time. Practicing calligraphy requires perseverance. I wish you success! Meihua
