How does Huang Tingjian evaluate Fan Zhongyan's calligraphy?

Huang Tingjian believes that Fan Zhongyan's calligraphy is "carefree and calm, very close to the calligraphy of Jin and Song Dynasties, and Su Caiweng's brushwork is better than the world, and he said that the calligraphy and calligraphy are homotopy, and the hook refers to the wrist, which is superior to the ancient statutes." This shows that Fan Zhongyan's calligraphy characteristics are also the representative of the Northern Song Dynasty people's "entering the ancient statutes".
