The second step is to practice the basic writing method of seal script and learn the principle of seal script. You can learn and write according to part of Xu Shen's book Shuo Wen Jie Zi.
The third step is to stick to calligraphy. Learn Taishan stone carving first, and then learn Zhao or Deng's seal script.
The word-making of seal script is different from modern Chinese characters. In the process of practice, we should refer to some books about the origin and meaning of Chinese characters to avoid making things up. In addition, it is not appropriate to use a blunt file pen tip when practicing Xiao Zhuan, which is easy to flow into the craftsman spirit.
