I'll tell you the cheapest and easiest way, but you have to be able to bear hardships and buy some training bottles and halls. Taobao can be sold back. You can just watch online videos and practice at the primary level. First, you can search for the teaching video of bartender Yu Yang, and then search for two bottles, one bottle, one hall, three bottles and four bottles. I regret spending fifteen thousand dollars at school. In fact, you can practice by watching videos and thinking more. Then I can go to the bookstore to buy some cocktail books and recipes, where there is theoretical knowledge. There are signs of alcohol in the restaurant. Just know that you don't have to worry about education. Foreign wines are written in Chinese at the back, and there are also wine recipes in the book. Then you can find a bar to work and see how well you know. Practice more fancy, just find a lawn to practice. Bartender is the secondary ingredient. Just remember those who died.
