Su Shi was the first to praise Mi Fei to the sky. In the book review, he called it "a calm and happy horse, which not only deserves to keep pace with Zhong and Wang." Mi Fei, like Zhong You and Wang Xizhi, was promoted to the highest level in China's calligraphy history. The word "calm and happy" has also become the most famous and distinctive label of Mi Fei in the past thousand years.
Since the Northern Song Dynasty, another friend of his, Huang Tingjian, has given Mi Fei the most objective, accurate and appropriate evaluation. There are many records about the friendship between the two people in history: Mi Fei got a gold medal and was addicted to life. He boasted that he was on a business trip and wrote a banner on the boat, "Jinbao Zhai Fang". At this time, Huang Tingjian was exiled to Jingzhou, thousands of miles away, and he was fascinated by it: "Wan Li sails in the sky, and Musk Tail flies to pay New Year greetings. When the Lancang River is bright overnight, it must be the Mijia painting and calligraphy boat. " This elegant old story is still passed down as a beautiful story.
Therefore, Huang Tingjian's evaluation can be described as commendable: "I have commented on Mi Yuanzhang's books, such as a sword, which shoots thousands of miles with a strong crossbow. When penetrated, the calligrapher's brushwork is also poor." However, Zhong You didn't seem to see Confucius. "Looking at Mi Fei's life experience and pursuit, he is addicted to painting and calligraphy, inviting him to spoil him, which is also vulgar and elegant, and rarely considers the truth of the world, society and life. This is not only incomparable with Erwang and Yan Zhenqing, but also incomparable with Su Dongpo of his time.
