Historically, mysterious characters were popular and circulated among women in Jiangyong County, Hunan Province, China and its neighboring counties, Dayaoshan in Jianghua Yao Autonomous County and parts of Guangxi, and men could not understand the meaning of these characters. However, with the development of the times and the improvement of women's education, women's books are facing extinction. Nvshu is only used by some rural elderly women and is on the verge of extinction. 1982, Professor Gong Zhebing of Wuhan University discovered female calligraphy in Jiangyong County, Hunan Province, which shocked the world. Nvshu, strictly speaking, should be called Nvshu, which is a strange set of Chinese characters. It is unique not only in symbol form, recording language, marking language and means, but also in popular areas, social functions and inheritance history. Nvshu is popular in Xiaoshuigu, Jiangyong County, Hunan Province, and is still used by some elderly women. There are several local stories about the origin of women's calligraphy. One of them says: Since ancient times, women in Xiaoshuigu, Jiangyong like to get together to weave and embroider. They can't go to school to learn male characters (they call square Chinese characters male characters). In order to write down their sufferings, they jointly created such characters on the basis of weaving embroidery patterns. Nvshu is born out of square Chinese characters and is a variant of square Chinese characters.

Xie Zhimin, the author of "The Mystery of Jiangyong Nvshu", analyzed the similar relationship between Nvshu and ancient Chinese characters, as well as the ancient cultural characteristics of some writing structures, and put forward that Nvshu, which was circulated among women in Shangjiangwei, Jiangyong County, was a relic of a very old writing, not something from the Song and Yuan Dynasties, but existed at least in the Yin and Shang Dynasties more than 3,000 years ago. Jiangyong Shangjiangwei area was a place where ethnic groups blended in ancient times. Today, among the local residents, not only the Chinese dialect they speak has left the "bottom" of the ancient Vietnamese language, but also the customs of the Han nationality still leave obvious customs of crossing the wind, learning from Chu and practicing Ba. Therefore, it cannot be ruled out that the' Nvshu' series of characters circulating among women in Shangjiangwei, Jiangyong may be the legacy and evolution of ancient Baiyue characters, Chu characters or Ba characters, especially the legacy and evolution of ancient Baiyue characters. "Mr. Xie Zhimin pointed out that' Nvshu' records the dialect of Shangjiangxu in Jiangyong dialect, but there are obviously some morphemes, words and grammatical structures in' Nvshu' and its recorded dialects belonging to Zhuang and Dong language families."

Later, there was a problem: the spread area of' Nvshu' was far away from the residents of all ethnic groups who spoke Zhuang and Dong languages. Where do these language elements and grammatical structures in Nvshu come from? As we all know, after the Chu people conquered Hunan, the Yue people living in northern and central Hunan were either eliminated or exiled to the south. The Vietnamese who settled in southern Hunan continued until the Han Dynasty. With the increasing persecution of the Vietnamese by the Han ruling class, they migrated to the south or southwest, becoming the main source of Dong people in the adjacent areas of Hunan, Guangxi and Guizhou today. Guangxi Zhuang nationality is also a branch of ancient Baiyue. The evolution and development of Nvshu is a language phenomenon of differentiation and aggregation. Nvshu and Zhuang-Dong language family are "homologous differentiation" of ancient Baiyue language. Nvshu and recorded dialects are similar to some morphemes, words and grammatical structures of ancient Baiyue language preserved by Zhuang and Dong languages, and Nvshu and Chinese are "heterogeneous aggregation", thus forming "recorded yes". Can the above inference be used as another evidence that Nvshu is "the legacy and evolution of ancient Baiyue language"? I have to accept other people's comments.
