What font is the picture? What copybook should I practice this word?

This is a hard pen free body! There is no such copybook to buy, because it does not form a family style, but it is similar to the "two kings" style of soft pen calligraphy. Hard-pen calligraphers are famous for their strength: Tian Yingzhang, Pang Zhonghua, Si Mayan and Li Fangming. And each has a different style. Among them, Pang Zhonghua has a book called "Multi-body Hard Pen Calligraphy", which is somewhat close to the words in your picture. The main font in the book is his own, and the styles of famous artists such as Wang Xizhi and Miti are copied with hard pen. You can go to a large bookstore. I believe you will be satisfied! It is best to buy and Pang Zhonghua (Huang; Ponzi's running script is also great, so I won't say much. We'll see! Just compare the factions! (Liu Zhihui Yin Mo Pastoral)
