Yang Xin, Wang Xianzhi's nephew, studied calligraphy under Wang Xianzhi. Official script, calligraphy and cursive script were all very good, and they were very famous at that time. He was rated as "Wonderful Moment" and "Best Wang Ti". There was a popular saying at that time: "Buy a king and get a sheep." However, compared with Wang Xianzhi's book, there is a big gap. Liang Wudi's On the Advantages and Disadvantages of Ancient and Modern Scholars gave Yang Xinshu the most incisive evaluation. He said: "Yang Xinshu is a wife like everyone else. Although in his position, he is shy and seems unreal. "
Yang Xin wrote a book about the history of calligraphy named from ancient times. Handed down calligraphy works include late spring posts, grand view posts, casual posts and so on.
