When it comes to fonts in the Sui and Tang Dynasties, we have to mention the period from 581 to 97, in which 37 years from 581 to 618 was the Sui Dynasty and 289 years from 618 to 97 was the Tang Dynasty. The Sui and Tang Dynasties, together, were only 326 years, but they were called the prosperous times in China's history, and the cultural products derived from the prosperous times were unprecedented.

Of course, first of all, it must be emphasized that our common simplified Chinese was launched in the mid-195s, and it was mainly used in Chinese mainland and overseas Chinese communities. Therefore, in all previous periods, traditional Chinese, as opposed to simplified Chinese, was basically used, and in addition, regular script was widely used among the five fonts of calligraphy in Sui and Tang Dynasties, so we can know that the font used in Sui and Tang Dynasties was traditional regular script.

However, because regular script evolved from official script, and calligraphy in Sui Dynasty inherited the style and vigor of Southern and Northern Dynasties, it has a clever and integrated font seen in later generations. In this regard, Mr. Sha Menghai, who is known as the master of the 2th century, even subdivided it into four categories, which will be discussed in detail later. The calligraphy in the Tang Dynasty not only inherited the essence of the fonts in the Sui Dynasty, but also regularized and matured them, so that famous artists came forth in large numbers at this time, among which I think Yan Zhenqing was the most famous.

Of course, students who have studied calligraphy must know that there is a famous saying in calligraphy: "When you learn a book, you must start with a letter, and when you write a word, you must start with a big character. Chinese characters are based on Yan, Chinese characters are based on Europe, Chinese characters are familiar, and then they are gathered into small characters, and Zhong Wang is the law. " Therefore, it can be seen that it is appropriate for this beginner to learn Chinese characters, and the copying model of Chinese characters is mostly Tang Dynasty calligraphy, especially the regular script of Ou Yangxun, Yu Shinan and Chu Suiliang in the early Tang Dynasty.

It can be seen that this inherited the vigorous fonts of the Sui Dynasty in the Southern and Northern Dynasties, which laid a good foundation for the vigorous and neat fonts of the Tang Dynasty, so that we can still see such quaint calligraphy works now.
