I have been practicing Zhao Mengfu's running script. When should I change my post?

First: I think it is enough to be able to create calligraphy works with Zhao Ti. The premise is to master the essence of Zhao Ti, not just to write images. Spirit is the highest state.

Second: then practice other running script copybooks, and then meet the same requirements mentioned above.

Third: whether you can become a calligrapher depends on proficiency. If you combine Zhao Ti with Su Ti Shen, that is, the brushwork, and write your own face, this is the real calligrapher. Make every calligrapher's handwriting more similar and more energetic, but he is not a calligrapher. A real calligrapher must write his own face on the basis of making the past serve the present.
