How does Huang Tingjian evaluate Fan Zhongyan’s calligraphy?

Huang Tingjian believes that Fan Zhongyan's calligraphy is "quick and calm, very close to the calligraphy of the Jin and Song dynasties. Su Caiweng's calligraphy is wonderful in the world. He only calls Wenzheng Gongshu the same method as "Le Yi Lun". The cover of the calligraphy is hooked and pointed back to the wrist. All of them are excellent and conform to the standards of the ancients." This shows that Fan Zhongyan's calligraphy characteristics are also representative of the Northern Song Dynasty people's "conformity to the standards of the ancients."
