2. In the history of calligraphy, when it comes to calligraphy in the Song Dynasty, there are four major calligraphers: Su, Huang, Mi and Cai. The four of them are considered to be typical representatives of the calligraphy style of the Song Dynasty. Among the "Four Song Schools", the first three refer to Su Shi (Dongpo), Huang Tingjian (Fu Weng) and Mi Fu (Xiangyang Manshi). From the perspective of calligraphy style, Su Shi is plump and innocent; Huang Tingjian is vertical and horizontal, high and hidden; Mi Fu is handsome and bold, calm and happy. They were all good at learning from the ancients and full of innovative spirit. Their calligraphy style was unique and highly praised by people at that time. They were listed among the four schools without any objection. It is generally believed that the so-called Cai refers to Cai Xiang (Jun Mo). His calligraphy is based on the Jin and Tang Dynasties, and pays attention to ancient meanings and laws. However, some people think it is Cai Jing. Who exactly he refers to has always been controversial.
