Who first put forward the song style?

Song Zi was originally created by Qin Gui in the evaluation of Chinese calligraphy in past dynasties. Calligraphy and character are a flesh-and-blood whole, and character has always been higher than calligraphy. Calligraphy is a highly integrated expression of knowledge, talent and quality of fever. Sima guang once said: only those who win virtue are also villains. Many people think that collecting the calligraphy works of calligraphers with low character is tantamount to collecting evil spirit, which not only defiles the family style, but also harms their own character. Therefore, treacherous court official Cai Jing, Qin Gui, Yan Hao, etc. can be called great calligraphers, but few of their calligraphy works have been handed down, so-called words are wasted because of people. Zhang Ruitu's attachment to Yan Dang is different from Yan Artemisia in nature.
