What is Miffy's hobby? What are the characteristics of his calligraphy and his unique experience in calligraphy?

Mi Fei's hobby: Mi Fei likes stones and inkstones. I like to wear Tang suit, and I am addicted to cleanliness. Mi Fei's calligraphy is characterized by unrestrained style and rigorous statutes. In addition, there are often sideways postures in calligraphy, meaning first left and then right, first lifting and then restraining, all in order to increase the ups and downs, flying air, naive and natural, never artificial. Mi Fei's understanding of calligraphy: He has a unique understanding of the distribution, structure and pen use of calligraphy. The requirements are "stable, not strange, not old, not fat", which is probably what Jiang Kui wrote "no sag, no shrinkage, no going." That is, it is required to achieve unity in change, and to integrate the opposing factors such as wrapping and hiding, fat and thin, sparse and dense, simplicity and complexity, that is, "bones and muscles, meat and fat, and charm are all there, just like a good scholar." In composition, attention is paid to the overall charm, the perfection of details, ingenious conception, changing with the situation in the writing process, and ingenuity. Mi Fei's pen-using characteristics are mainly good at forming elegant and extraordinary momentum and calm and happy style in the face, retrogression, turning and frustration. The beginning of the word is often quite heavy, and the middle is slightly light. When the side of the pen encounters a turning point, it will go straight down. There are also many changes in holding the pen. The focus of the next stroke is sometimes on the pen, sometimes on the pen, and sometimes in the middle of a stroke, a long horizontal painting has twists and turns. Hooks are also very distinctive.
