In China Taoism (No.2, 2003), Yang published an article about the origin of South China, which mentioned another evidence, that is, the name of South China appeared before Xuanzong of the Tang Dynasty. Yang Jiong, one of the four outstanding figures in the early Tang Dynasty, wrote in the Tombstone of Baiquan County Order in Yuanzhou: "I came back with Xuan, Huang Zhongxiu, Sun and Moon, and I didn't live there, so I retired." South China is also a teacher, and my new home is cheap; Oriental talents are also humble. "The article also pointed out that eight" Southland Theories "were quoted in the Untitled Taoist Classics on page 2390 of Dunhuang manuscripts (see Huang Zhu's Dunhuang Treasures, Taipei New Style Publishing Company, 1985, vol. 120, pp.179-/kloc-0. ), Wen Yang thinks that in these quotations, "except for a few words that are slightly different from the popular Zhuangzi, they are generally the original Zhuangzi. Therefore, The Theory of South China is about Zhuangzi, and The Theory is Liang Kuang's comment or explanation on Zhuangzi. To be sure, the' South China Lun Yun' quoted in the Lost Collected Taoist Scriptures by P.2390 comes from Liang Kuang's book On South China. "

It can be seen that Zhuangzi was called "South China" before Xuanzong of the Tang Dynasty, which was probably called by more and more people, so that it was officially recognized only when Xuanzong was in the Tang Dynasty. Annals of Sui Shu Classics: On South China, 25 volumes, written by Liang Kuang, 30 volumes. Sui Shu was compiled by Wei Zhi during the reign of Emperor Taizong. At that time, "On South China" had been lost for five volumes, so it was quite a long time before the Tang Dynasty, and its author should be Liang Kuang who annotated "Lao Zi" with Lu Jingyu.

As for why Zhuangzi is called the South China, Mr. Chen Yingning also mentioned in the article "Chapter of the Classic of the South China": "Those who note" Zhuangzi "also quote the cloud in the Collection of Notes by Wang Jia of the Eastern Jin Dynasty:' Zhuangzi, the word Zi Xiu, is famous as the South China Zi' ... but the article' Zhuang Zhou' is not. South China Zi can't be found in this edition of Notes. The annotator also said that Zhuang Zhou lived in seclusion in Huashan, south of Cao Zhou, so his name "Nanhuajing" was also questionable. " Mr. Chen Yingning thinks that "Nanhua County is named in Zhuangzi" through the textual research of Geography of Old Tang Dynasty ... Since the county name can be changed, can't the mountain name be changed? There is no need to have a mountain name before a title. "

It is difficult to confirm where South China came from. But I personally suspect that "South China" may have the same name as "Donghua Dijun". During the Six Dynasties, Shangqing Daoism flourished, and there were many descriptions of immortals' abode of fairies in Shangqing Classic, and Donghua was one example. "South China" originated from this era. Perhaps this Taoist trend of thought has been influenced by the pure land thought of Buddhism. Lu Jingyu, who annotated Laozi with Liang Kuang, is also a Buddhist. They may belong to northerners and regard Zhuangzi as a southerner. But all the above are speculations.
