As far as learning regular script is concerned, Europe, Yan, Liu and Zhao, which are highly respected by Chinese people, are all good models. However, according to your needs, it is recommended to learn from Jiuchenggong in Ou Yangxun, because among the four regular scripts, the regular script characters of Yan Zhenqing and Liu Gongquan are not easy to be converted into running script, while the calligraphy styles of Ou Yangxun and Zhao Mengfu are the blood of two kings, which can lay a good foundation for learning running script. However, it is generally believed that Zhao Mengfu's calligraphy lacks bone strength and is not suitable for beginners, while Ou Yangxun's regular script method is extremely rigorous, which can help you lay a solid foundation. Therefore, I recommend Ou Yangxun's Ninety percent Palace.
(2) The problem of "brush-like" writing brush.
Everyone who is a beginner in calligraphy will encounter this problem about "brush", which is why we began to think about "brushwork". To put it simply, in the hands of the ancients, in the process of writing, the brush kept rotating and constantly adjusted the angle to complete the ideal stroke shape. Miffy's "Eight Faces Out" is the highest realm of writing. In other words, when we look at the ancient copybooks, we should constantly ponder how the ancients skillfully adjusted the state between strokes, which is also the subtlety of China's calligraphy. It may be helpful to read Sun Xiaoyun's Calligraphy and Law. At the same time, you can watch more videos written by famous artists on the Internet, learn their writing skills, watch more and practice more, which will definitely improve greatly.
