Where can I buy traditional Chinese copybooks in Tianjin? Or where can I?
There is a copybook published by the Hong Kong Institute of Literature and Arts. The cursive script of Wang Xizhi that I copied now is also traditional.
Both of them are pen copybooks.
If you need calligraphy, you can buy a book written by famous calligraphers of past dynasties, see whose handwriting you like, and then paint the memorial tablet of that person in red.
