What is the font of the calligraphy written by Xia Ziwei in "Xin Huan Zhu Ge Ge"?

I have learned Zhao Mengfu's calligraphy. Zhao Mengfu's handwriting is light horizontally and heavy vertically, and the handwriting is a bit square. I carefully appreciate the small movements when he writes horizontally, and there is a small hook to write horizontally. , but I think the fonts are exactly the same, and there are no errors in the characters. It can be said that there is a little bit of Zhao Mengfu's font, just 20%. As for Wang Xizhi's, I don't know much about it
