There are many rumors about Ou Yangxun's obsession with learning calligraphy. One of the most representative stories is that when Ou Yangxun was young, he went out on a long trip and happened to see a stone tablet on the roadside in the wild, which was written by Suo Jing, a calligrapher in the Western Jin Dynasty. After reading it, I was moved, stopped to watch it for a while and continued on my way. After walking for a few miles, I couldn't put it down, so I went back and continued to observe the stone tablet repeatedly. Later, feeling tired, I sat down under the stone tablet. It was dark, so I spent the night beside the stone tablet. I was so addicted that I stayed for three days before leaving. Ou Yangxun's obsession and love for calligraphy made this experience a much-told story in the history of calligraphy. There is also a small allusion. Ou Yangxun usually attaches great importance to the collection and research of ancient calligraphy works.

This book contains the method of calligraphy with pen. Ou Yangxun was so happy that he bought it with 300 pieces of light yellow silk. After buying home, Ou Yangxun studied day and night, reading without sleep, which also caused a sensation at that time. Ou Yangxun loved calligraphy, learned from others and studied with an open mind. "After learning Wang Xizhi's book, I became a home." In his later years, he was vigorous and vigorous, and he had the wind of law enforcement and litigation. The butte rises and is cut into four sides, which is not a hollow name. "
