Hard pen calligraphy: practice with red copybooks or translucent paper copybooks in the early stage. You can buy sulfuric acid paper from Taobao, trace the original translucent paper on the copybook, and replace the original sulfuric acid paper with sulfuric acid paper. After the font has made some progress, if you can quickly trace the original font on sulfuric acid paper, use white paper or manuscript paper to copy it. Remember not to use printing paper, square paper is best (it can help adjust the spacing and spacing)
Brush and soft pen: It is useless to copy with rice paper and copybook (unless you draw hundreds).
