It is worth mentioning here that Mr. Zhu Guantian has the view that European books originated from Daling. He believes that according to the translation of Hu Jinji in Song Dynasty, "Ou Yangxun spent 300 yuan to buy a Guide to the Right Army". Enjoy menstruation, happy but not sleepy. So I started reading his books. From this point of view, Ou Yangxun started from the calligraphy of the right army and devoted himself to the map teaching of the right army. The map of religious offerings of the right army here refers to the literary theory of Wang Xizhi's godson Jing, which Zhang Yanyuan thought was false and was deleted. Sun's Book Score also includes "simplified characters, good characters and clumsy characters". The purpose of the item is not the record of the right army. Therefore, Mr. Zhu believes that if the record of Jin Ping Mei is correct, the beginner should be that Liang Chenren entrusted him by mistake. Liang and Chen's society is "more noble than other places in the world. They respect their children" ... and have a simple style. The calligraphy style of a person with the name Wang Zi must be similar to or beyond Da Ling. Look at Ou Yangxun's travel and cursive script again. He contracted the festival to collect money and release it, which originated from the big order. The theory of learning from the right army recorded in historical books may be due to the high standard fashion at that time and the taboo enshrined by Emperor Taizong.
In my opinion, both Ou Yangxun and Yu Shinan spent their youth in the Southern Dynasties. Later, in the Tang Dynasty after the Sui Dynasty, because Emperor Taizong strongly advocated being king, it was entirely possible that they were influenced by the calligraphy style and emperor's preferences of various times, so whether they dedicated it to Xi may not be completely conclusive.
