It talks about the four masters of Ouyan, Liu and Zhao Kaishu, namely Ouyang Xun, Yan Zhenqing, Liu Gongquan and Zhao Mengfu. The first three were from the Tang Dynasty, and Zhao Mengfu was from the Yuan Dynasty. If it is talking about Zangfenglufeng, then it may be talking about Yan Liushi, Wei and Jin Dynasties, or the situation is not yet complete. I don’t know what the speaker wants to express in the specific context. Learning from the Wei and Jin Dynasties means that Yan Liu, who studied regular script, also learned from the calligraphy of the Wei and Jin Dynasties. If we say that the momentum is not exhausted, it means that Yan Liu's calligraphy style is methodical, subtle and does not allow the brushstrokes to be rough and unrestricted. The next sentence should be able to be interpreted as saying that Ou Zhao Bingzhong Wang means Zhong Yao (Wei) and Wang Xizhi (Jin). It seems that the upper and lower sentences should have the same meaning, that is, regular script developed from the calligraphy style of the Wei and Jin Dynasties. Therefore, it seems more appropriate to describe Wei and Jin, the masters of the previous sentence.
