In fact, the main languages used in Guangxi are Chinese and Zhuang, and Cantonese is mainly distributed in Guangdong, Hong Kong and Macao and overseas Chinese communities. Although Guangxi and Guangdong border on each other, due to historical and cultural factors, there are great differences in language and culture between the two places, so Hechi generally does not speak Cantonese.
If you need to communicate or travel in Hechi area, it is recommended to learn local Chinese and Zhuang language in order to communicate with local people better. Of course, if you can speak Cantonese, you can also use it occasionally when traveling, but be careful not to rely on Cantonese for communication, so as not to create communication barriers.
