Yang Ningshi is an unavoidable figure in the history of China's calligraphy. Yang Ningshi was born in the late Tang Dynasty and lived in the Five Dynasties. In that split and iterative era, he was an official in Hou Liang, Tang Dynasty, Jin Dynasty, Han Dynasty and Zhou Dynasty, and he did a lot of work as an official. He is called Yang, which can be popularly understood as the emperor's teacher. This is a very learned job.
I think there are two main reasons why Yang seems to get along well in various imperial courts: one is because he is the second generation of officials and his father is the prime minister at the end of the Tang Dynasty. His family environment may have made his business more accurate than the word EQ, and his business seems to be higher than his father's, and he is by no means a master of cheating.
The second reason is that he is very hard on himself. In order to survive, he did not hesitate to pretend to be crazy, so it was not easy to live from the Tang Dynasty to the later Zhou Dynasty and to his eighties. This is actually related to his official business. Because he went crazy from time to time to save his own life, he also had a nickname in history, Yang Crazy.
It's just that Rainbow Xizhi is a high mountain, Yang Ningshi is another mountain below it, Wang Xizhi is the mother mountain, and Yang Ningshi is the son mountain. Later generations inherit from the main vein, and there is a lot of room for innovation and change, while the space for inheritance and innovation from the secondary vein is relatively small. Only by breaking free from more constraints can innovation be possible. So we often say that we can take the law.
