According to the "Old Book of Tang Dynasty", Ouyang Tong said, "As a young boy, his mother Xu taught his father how to write. Every time he passed the money, he said: 'Quality your father's calligraphy is straight.' Tong was very famous. , The energy is tireless day and night, so it is inferior to inquiry." It can be seen that Ouyang Tong's calligraphy originated from his family, and he learned from his father's calligraphy. "Shu Shu Fu" has the reputation of "following the beauty" and praised it: "The father is in charge of the rites of the country, and the son lives in the temple. With the changes of fortune, for The dragon is light”. Tong is also very proud of his calligraphy, and is especially particular about the Four Treasures of the Study. Zhang Zhujue's "Chao Ye Qian Zai" said: "If you are always serious about your calligraphy, you must use ivory and rhinoceros horn as the harmonious tube, raccoon hair as the heart, and then Autumn rabbit hair. Pine uses smoke as ink, and the end uses musk. The paper must be strong, thin, white and slippery, so it is the book. Although Ouyang Tong's regular script comes from his father, it is thinner, stiffer and more vigorous. Especially the horizontal strokes in the main strokes are lifted up at the end when the stroke is finished, which has a very strong official meaning. This has become a kind of his regular script. Characteristic, this kind of sharp edge is called "criticism" in calligraphy terminology. Liu Yuzai's "Shuji" states: "The large and small Ouyang calligraphy are both divided into official scripts. Since the stele of Guanlantai Road has a script, it is obviously official." The pen is gone." Ouyang Tong is good at using upward posture, back posture and sharp edge posture, so he can give people a spirited artistic feeling. Wang Shizhen of the Ming Dynasty wrote in his book: "The Stele of Daoyin is like a disease of Vimalakirti, a high-ranking and poor man, although he is not happy, but there is an aura of wind and frost between his eyebrows, which is serious." But the sharp edges and corners are too exposed, which contributed to his The characteristics of his calligraphy have also become the target of critics in the past. Yang Shiqi criticized his calligraphy for having "little implicit interest", and "Shuguan" said that his calligraphy was "thin and shy of being outstanding". This was in line with the aesthetic concept of "a gentleman hides his utensils" at that time. Relatedly, in fact, when the negative character of the art of calligraphy focuses on one aspect of yin and yang, it will inevitably ignore the other aspect. No matter how strict the rules of Ouyang Tong's regular script are, the writing force is clear and vigorous, the characters are elegant and straight, and the meaning is elegant. He is indeed a famous figure of his generation.
