1. Official script flourished in the Han Dynasty;
2. It became popular in the Han Dynasty, so the calligraphy circle is called "Han Li Tang Kai". It is said that the official script was compiled by Qin Weicheng Miao in prison, eliminating complexity and simplifying it. The character shape was changed from round to square, and the strokes were changed from curved to straight. The shape of the characters is beautiful, flat and wider. Officials, so in ancient times, the official script was called "Assistant Book". "There are many things to do, and it is difficult to complete the seal script, so I ordered the official to assist the script, which is called the official script." However, it is pointed out that the character "Li" also means "affiliate" and may mean a derivative of the seal character.
3. In the early Western Han Dynasty, the style of Qin Li was still followed. In the Xinmang period, major changes began to occur, and the stippling wave tail writing method was produced. By the Eastern Han Dynasty, official script had developed many styles and left a large number of stone carvings. "Zhang Qian Stele" and "Cao Quan Stele" are representative works of this period.
4. Han Li has the beauty of waves and zhe (zhe) in its strokes. The so-called "wave" refers to the strokes on the left that are like curved waves, which in later regular scripts become abbreviations; the so-called "Zhe" refers to the strokes on the right that are open and shaped like a swallow's tail. When writing long horizontal strokes, the strokes should start against the front and cut into the shape of a silkworm's head. The strokes in the middle should have a wave and pitch, and the strokes should have a tail at the end. In this way, when using the pen, all the methods of square, round, hidden and exposed are all ready, and the strokes are flying and the posture is graceful. Structurally, there is the vertical rectangular shape of Xiaozhuan, which first becomes square, and then becomes horizontally flat and square. Han Li has a majestic, strict, yet flexible and flexible style. The reform of official script to seal script includes two aspects: strokes and structure. The method of transformation is to change the circle into a square. Make the curve straight. Correct broken strokes. Reduce stroke structure and so on. Among them, taking the horizontal position and retaining the natural writing state of the brush are the most important. The potential energy is taken laterally to write left and right, and the up and down movement is restricted. Finally, the eight-point stroke technique of sweeping left and picking right was formed. The softness of the brush makes the strokes of Chinese characters appear thick and round. Various changes such as hiding dew. There is also wide kerning. Narrow spacing is also a major feature of its composition.
5. Han Li is exquisitely represented in silk paintings, lacquerware, portraits, and mirrors. And its broad momentum and unique charm are even more evident in the inscriptions. There are two main forms of Han Li: stone carvings and bamboo slips. Most of the official scripts in the Wei, Jin, Southern and Northern Dynasties were mixed with regular script; in the Tang Dynasty, there were many official scripts written by calligraphers such as Xu Hao. The official script of the Song, Yuan and Ming dynasties could not revive the glory of the Han Dynasty. Until the Qing Dynasty. Han Li was able to recover. There are Yu Nong, Deng Shiru, He Shaoji, etc., who have made outstanding achievements.
