I think Shu Tong’s calligraphy can be regarded as a real calligrapher, but there are still only a handful of them. There is no doubt that Chairman Mao’s own Mao style, Kang Sheng’s left and right bows, and Guo Moruo’s calligraphy God has it, and Shu Tong's calligraphy with the head and tail covered and the self-made seven-and-a-half body are all treasures of pen and ink in the world of calligraphy!
