Teacher's Day is coming. I want to send my teacher a calligraphy work. What should I write? (regular script)

Regular script, because of its simple style, quaint calligraphy style, rigorous statutes and rigorous structure, some are handsome and graceful, and some are graceful and elegant. Now commonly known as regular script, it evolved from Han Li, and can be divided into Weibei and Tang Kai according to the period. Weibei refers to the calligraphy style in Wei, Jin, Southern and Northern Dynasties. It can be said that this is a transitional calligraphy style from official script to Tang Kai. Very immature, there are often official scripts written in it. However, due to its immaturity, it has created a scene of flowers blooming, with various postures and formed a unique beauty. Kang Youwei commented on "Ten Beauty in Weibei". Regular script in a narrow sense refers to Tang Kai, which gradually matured after the Tang Dynasty. Its representatives are Ou Yangxun, Yu Shinan, Jun Yiliang and Xue Qi in the early Tang Dynasty, Yan Zhenqing in the middle Tang Dynasty and Liu Gongquan in the late Tang Dynasty. We often say that the four masters of regular script "Yan Liu Ou Zhao", the first three are all from the Tang Dynasty. By the end of the Tang Dynasty, regular script had reached its peak and its style was too regular, so it gradually declined. In the Song Dynasty, Su Shi, with his poetic demeanor, created a rich and naive "Su Ti", which can be called "the first in the Song Dynasty". At the end of Song Dynasty and the beginning of Yuan Dynasty, Zhao Mengfu U formed "Zhao Ti", that is, "Zhao" among the four families, but "Zhao Ti" should be strictly a running script, not a regular regular regular script, so beginners generally start with "Yan", which is also recognized as the correct way to learn books. Next, I will compare the three-body from many angles, and some angles also refer to Wei Bei and Zhao Ti, so as to fully understand the regular script individuals. The above comparison focuses on the style characteristics of Yan, which is influenced by both the times and personal factors. For example, the European style was formed in the early Tang Dynasty and was greatly influenced by Weibei. Influenced by the aesthetic view that fat is the beauty in Tang Dynasty, the face is full. And Liu Ti, because of Liu Gongquan's integrity, "people are upright and upright." In short, it is also a subject worth studying to fully understand the characteristics of calligraphy.
