2. Seal: refers to the seal that was popular from the end of the Warring States Period to the beginning of the Western Han Dynasty, and the language used is Qin Zhuan. Printing has a great influence on seal cutting, among which white printing is the most representative. Among them, all-white printing such as "guarding the city in the east of the town" and "clever Sima" is vigorous and simple, and the brushwork is naturally interesting and impenetrable, which has a strong poetic effect.
3. Bao: According to the Records of Tang Shuyu Prefecture, Wu Zetian changed her surname to Bao in the first year of Yan Zai because she thought that "feng" and "death" were homonyms. Later, Tang Zhongzong acceded to the throne, using the old "seal" and "treasure".
4. Chapter: In the Han and Wei Dynasties, the general print was generally called "chapter". The general went to war in a hurry, his seal was exquisite and peculiar, and his sharpness stood out among general print. It was carved in a hurry by a temporary appointment on the way to March, which is called "urgent chapter". It has a unique style and has a great influence on the development of seal cutting in later generations.
5. Records: "Records" generally have two names. There are also "Ji" and "Zhu Ji" in the official seals of Tang and Song Dynasties. In the official seal of the Song Dynasty, "You Ce Ning Zhou stationed in Zhu Ji" includes "Jian Yan Zhu Ji of Suzhou State Courtyard" and "Teaching and Reading Loyalty Festival, Order No.23, Zhu Ji No.3", all of which show the existence of history. Seal has always been the representative of honesty. With the evolution of historical rings, it has formed a complete system and left a strong mark on China's tradition of more than 5,000 years.
