1, Pang Zhonghua: the pioneer of China coin calligraphy and the master of pen calligraphy. I recommend his "Talking about Learning to Write with Pen" and "Pang Zhonghua Pen Copy".
2. Si Mayan: Inheriting his family studies, he has a good writing style. There are many copybooks published by him describing red and copying in the market.
3. Tian Yingzhang: He also inherited his family studies and has profound writing skills, mainly including Tian Yingzhang's series of selected works of Copybook for calligraphy and Tian Yingzhang.
4. Lu Zhongnan and Copybook for calligraphy are all very good.
The above coin calligraphy is worth learning and you can buy it according to your own preferences!
In addition, if a worker wants to do a good job, he must sharpen his tools first! Choose a good pen with moderate price and excellent writing. You can search Baidu for the world's top ten classic pen brands (with the origin of pens and simple selection and maintenance methods), which contains a very complete set of pens and selection methods, all of which are some practical skills I personally compiled.
