I think Tian Yingzhang is the best pen copybook. His handwriting is full of rivers, upright and orthodox, and has no strong personal style. It is a rare and good copybook for those who learn hard pen calligraphy. Then Li, hehe, a little personality, I like it. As for Pang Zhonghua, he was the first calligrapher in China in those days, but now it seems that his personal style is still too strong. If you learn his handwriting, others can see that he is a pang at a glance.
If you want copybooks, go to Xinhua Bookstore to buy them. Ten yuan a book, benefit for life ~
