As far as I know, bartending in Guangxi is relatively backward, so it is estimated that there is no bartending school. If it is unrealistic to study in Guangxi, you have to go out of Guangxi to study. Professional bartending schools are generally found in first-tier cities with developed entertainment industry. As for the tuition fees you mentioned, they are all tens of thousands, and not all schools are like this. The Chengdu Horizon Bartender School I know is good and quite famous in China. They charge 6900 yuan to learn English fancy, which is quite cost-effective. You can get to know it.
