What are the characteristics of Su Shi's calligraphy?

When it comes to calligraphy, I believe that many people first think of Su Shi, our great talent, and Su Shi's calligraphy has many artistic features, such as charm and innocence, disparity in size, loose brushwork, horizontal light and vertical weight, flat and rich words and so on.

Moreover, if you carefully read its calligraphy, you will find that her calligraphy from early middle age to her later years gives people different feelings. She was influenced by her father in her early years, and calligraphy was a pleasure for him to write, so it was very charming to write. When she reached middle age, she was depressed and broad-minded, so she was full of energy when writing. In her later years, she experienced many things and gradually calmed down.
