Wang Xizhi of the Eastern Jin Dynasty practiced calligraphy very hard and once dyed the lake with ink. Mi Fei in Song Dynasty had many hobbies, besides poetry, calligraphy and painting, he also liked strange stones very much. He is good at observing things, and can find their exaggerated, grotesque and changeable aesthetic characteristics from the stones that people are used to, and get beautiful enjoyment and fun from them.
He knows nothing about Dr. Tai Chang's army. When he first arrived at the official office, he saw the unique stone standing in the state capital. He was ecstatic at the moment, so he asked his entourage to bring him a robe, put on official clothes and insisted on boarding. For example, he bowed to the strange stone line as a gift to the supreme, and called it "Zhang Shi".
