Why is the calligraphy of the chairman of the Provincial Book Association very cheap?

To spread culture, people who like calligraphy can afford it.

As we all know, Shu Tong, the chairman of the first China Book Association, took the circle as the main body as a whole. On the basis of absorbing ancient methods, he made innovations to the maximum extent and formed his own style and characteristics, which was later called "Shu Tong Style". So was the calligraphy of Mr. Qi Gong, the chairman of the second China Book Association. On the basis of Liu Kai, his calligraphy fully absorbed the essence of Liang, a great calligrapher in Qing Dynasty, and gradually formed in the long-term calligraphy practice.
