Yan Zhenqing's copybook can be practiced, which is very suitable for beginners to practice. It's just that the basics and many people can't write well.

Wang Xizhi's Preface to the Orchid Pavilion and Huai Su's Weeds are both famous, so you can practice according to your own preferences.

I suggest practicing regular script first, because the foundation is very important. If you write with a brush, the recommendation word should be slightly larger. If possible, try to stand and write in the right posture. If your hands are shaking, put your elbow on the table and sit down to write.

If you write with a pen, you should have a writing brush when you hold it. If you show it, it will be beautiful. . . If you have a personalized signature, you can find someone to design it.
