What font is Xia Ziwei's calligraphy in Gege, New Zhu Huan?

I have studied Zhao Mengfu's calligraphy. Zhao Mengfu's handwriting is horizontal and light, vertical and heavy, and his handwriting is a little square. If you carefully taste his horizontal strokes, there is a small tick, but I think the font is exactly the same and there is nothing wrong with the words. It can be said that Zhao Mengfu's font is only 20%, but I don't know much about Wang Xizhi's.
