In the middle of Ming Dynasty, with the rise of Wumen Calligraphy School, the calligraphy circle of Ming Dynasty, which was bound by the calligraphy style of Yuan people for a hundred years, gradually entered the best state, thus opening a quite wonderful scene in the history of calligraphy in China. At this time, the calligraphy activity center has gradually moved from Beijing to Suzhou in the south of the Yangtze River.

Suzhou, as the capital of the three Wu dynasties in history, is rich in wealth and outstanding in people. It is not only prosperous in economy, but also a gathering of scholars, which has created a large number of outstanding painting and calligraphy artists and formed many painting and calligraphy schools. "Wumen Calligraphy School" is one of them. On the surface, the efforts of "Wumen Calligraphy School" are aimed at restoring the tradition of "the original form of each character" and taking truth as grass, but in fact they are aimed at and correcting the abuses brought by "Taige Style" calligraphy. Through the efforts of Song Ke, Xu Youzhen, Shen Zhou, Li Yingzhen, Wu Kuan, Qin Wang and others, it reached the stage of "Four Great People in Wuzhong" represented by Zhu Yunming, Wen Zhiming, Wang Chong and Chen Chun, and this school reached its heyday. There is a saying that "the calligraphy in the world belongs to Wu".
