Does Guilin speak Mandarin? I'm afraid it's not convenient to communicate there

Does Guilin speak Cantonese? Joke! I speak Guangzhou and Guilin dialect!

Guilin uses the northern language family, which is similar to Sichuan, Yunnan and Guizhou dialects. People in Guilin speak Mandarin better than those who speak Cantonese. But the Mandarin spoken by most Guilin people is called Southern Mandarin, that is, there is no difference between flat tongue sound and tongue sound.
