Pen Copybook for calligraphy Taobao branch

Tian Yingzhang's "Practical Course of Running Script, Regular Script and Famous Pen Calligraphy" is sold online, and the two fonts are combined in one book. It's convenient to spend 20 yuan on 500 sheets of paper to practice calligraphy, which is what I'm doing now. Taobao searched Tian Yingzhang, and a lot came out, including copybooks and books. Practicing with books is definitely more expensive than copybooks, but the advantage is that you write down how to collect each stroke in the book. Personally, the effect of book+copy paper is much better than copybook.
