Is it difficult to learn seal script without calligraphy skills?

If you don't have the basic skills of calligraphy, it is very difficult to write Xiao Zhuan. I have been engaged in calligraphy teaching for some days, and I have higher requirements for the line sense of seal script. People who don't have basic skills can't write that kind of fine texture, and I myself went from Xing Kai to Caozhuan on the road of learning calligraphy, so I accumulated experience. It is not good to write seal script directly without practicing calligraphy. I suggest you start with regular script and lay a good foundation. Chu Suiliang's running script is very good I recommend some books to you, such as Preface to the Wild Goose Pagoda, Yin Fu Jing and Ni Kuanzan. These copybooks should be copied repeatedly, and your delicate texture will be reflected in a few years. At the same time, we should combine the practice of running script, such as preface to the holy teachings of Wang Xizhi and biography of Wang Xizhi to help each other practice two words.
