Main reasons:
Zhong You's seal script, official script, original script, running script and cursive script are all part-time, and the best one is regular script. Xuanhe Pu Shu commented: "Prepare your statutes and be the father of official books." Zhong You lived in a period when Chinese characters evolved from official script to regular script and were nearing completion. In the process of the completion of this important evolution of Chinese characters, Zhong You played a powerful role in promoting. Therefore, it is called the originator of regular script. After Zhong You, many calligraphers competed to learn the clock body. For example, Wang Xizhi and his son have various clock styles. Later Zhang Chang, Huai Su, Yan Zhenqing, Huang Tingjian, etc. They all absorbed the length of the clock body and the essence of the clock theory from all aspects in calligraphy creation. This shows the influence of Zhong You.
