What are the artistic features of Mid-Autumn Festival stickers?

Mid-Autumn Post is a paper book with 3 lines in cursive script and 22 characters. Qianlong regarded it as one of the "three wishes" and now it is collected in the Palace Museum. Wang Xianzhi's "one stroke" continuous cursive style has been fully demonstrated in this article. Because some people say that Mi Fei is good at copying ancient posts, he fills the original with his own fakes. His works have the style of calligraphy of Song people, but lack the charm of Jin people.
