Zhao Mengfu once had a profound insight into learning Yan: "In modern times, when in Rome, do as the Romans do, and everyone likes to learn Yan Shu. Yan Shu is a great change for calligraphers, and the boy Xi often can't change until he grows old, becoming a bloated and fleshy disease, and there is no cure. " Zhao Mengfu's words are profound and worth pondering.
As for Song Sijia, this is another evil, and the evil is not in Song Sijia. In the past, people said that the Tang people respected the law and the Song people respected the meaning, which was what they meant. Su Huang Camo, four people, is famous for their running scripts. Among them, Cai Xiang is the best official book, but compared with the sages before Jin and Tang Dynasties, it has been greatly inferior. The brushwork of the four people is not the best in all previous dynasties. Later generations learned from these four schools and built towers on the sand.
Song Gaozong once lamented: "Since Shaoxing, among miscellaneous books and gossamer books, only Qiantang Wushuo and seal cutting are only Xu Jing in Xinzhou, which is no more than that. Alas, its disadvantages are also." During the Southern Song Dynasty, the disadvantages of learning from Song Sijia gradually emerged, and the book world gradually became silent. The innovation of book style was started by Zhao Mengfu in Yuan Dynasty under the banner of restoring ancient ways.
To sum up, the world loves Yan Zhizhong and learns his books, instead of exploring the source of Yan. It is naturally difficult to learn beauty in this way. Song Sijia also has its own subtleties, but if its own foundation, education and talent are insufficient, it is really fishing for the moon in the water.
