Who is the founder of Zhuang language? Do all Zhuang people speak Zhuang language?

It is generally believed in academic circles that the local folk characters of Zhuang nationality began in the Tang Dynasty, and the ancestors of Zhuang nationality absorbed and imitated the six-character square characters and created the "local folk characters", also known as "square local folk characters" or "sawndip". Some of these characters are recombined by using the radicals of Chinese characters, some are borrowed from Chinese characters to annotate the sound and meaning of Zhuang language, and some are hieroglyphics created. Phonetic Zhuang language came into being in 1950s. After the founding of People's Republic of China (PRC), in order to improve the scientific and cultural level of the Zhuang people, the China Character Reform Committee helped the Zhuang people to create phonographic Zhuang characters. This set of phonographic Zhuang language takes Latin letters as the letters, northern Zhuang language as the basic dialect, and Wuming County Zhuang language pronunciation as the standard pronunciation. 1957165438+1On October 29th, the State Council adopted the Zhuang Language Program, which was approved for trial implementation in Zhuang areas.
