Why do I write calligraphy on the edge paper, and calligraphy will permeate the paper? How to write so as not to penetrate? Is it ink? Or because you can't write in Chinese calligraphy?

We all practice with paper edges and throw them away when we finish writing. Penetration embodies the principle of penetrating the back of paper. This is good, but it also has something to do with ink. If too much water is added to the ink, it will be particularly easy to penetrate, and even after writing, the paper will be wet and black. It is suggested to add some water according to the font to be written.
