According to Yu Yuanwei, a calligrapher in the Liang Dynasty in the Southern Dynasties, in On Books, "The anti-Zuo Shu was created by Kong Jing Tong, a bachelor of Oriental Palace in Datong (534 -546). When I saw it, I reached it, so I rewarded all the people who knew it, and I called it the leisure method of the masses. Today, there are a little more scholars, and those who solve it are beneficial. " Chen Si of the Southern Song Dynasty, who wrote Bao Ke Cong Bian, noted in the Book Brief History: Kong Jing can write a cursive script, break a line, be graceful and romantic, and be unique in nature, and there will be no successors in the future. It was also created as a book about the left and right. At that time, those who were not knowledgeable should reach it in Yuan Wei's view, so they called it the leisure method of the public. " Yu Yuanwei said that "anti-Zuo Shu" was initiated by Kong Jing Tong during the period of Datong in Liang Dynasty. However, Xiao Shunzhi and Xiao Jing were both buried in Datong, and the time when their Shinto pillars were established should not be too long apart. Therefore, the statement that "anti-Zuo Shu" began with Kong Jingtong is obviously inaccurate. The actual situation is that "anti-Zuo Shu" appeared in the early years of Liang Dynasty, prevailed in Datong years, and then disappeared, becoming a masterpiece in the history of China calligraphy.
