Do Buyi people in China have written language?

Buyi people have their own language, belonging to the Zhuang and Dong language family of Sino-Tibetan language family. In the course of historical development, the Buyi language has formed three dialect areas: Wangmo, Ceheng, Anlong, Zhenfeng, Xingyi, Xingren, Luodian, Pingtang, Dushan and Libo, which belong to the first dialect area. Huaxi District, Guiding, Longli, Anshun, Pingba, Huishui and Changshun counties in Guiyang belong to the second dialect area. Zhenning, Guanling, Qinglong, Liuzhi, Panxian, Shuicheng and other counties belong to the third dialect area. Due to long-term contact with the Han nationality, Buyi language has absorbed many Chinese words. Buyi people didn't have their own national characters in the past. However, some folks use Chinese journalists or make up some vernacular to record Buyi ancient songs or Buyi scriptures recited by wizards, which is called "Chinese Buyi language". Its application scope is very small, and it has not been popularized among Buyi people. In 1950s, the people's government organized experts to create a phonetic symbol based on Latin alphabet-Buyi language in 1956. And it has been piloted in some Buyi areas. Discontinued in the early 1960s. From 198 1, Buyi language was gradually implemented in winter. After several revisions, a relatively perfect Buyi language was finally formed in 1985. Since the implementation of Buyi language in the Buyi area of Guizhou in the early 1980s, good results have been achieved. Especially in remote Buyi mountainous areas, the implementation of Buyi language has played a positive role in improving children's enrollment rate, enrollment rate and adult literacy rate.
