I want to be a pianist in a western restaurant or hotel, but I have no experience, I don't know what to play, and I don't know how to be a capital.

First, sharpening the knife does not mistake the woodcutter. First of all, visit various western restaurants or hotels to see what pianists there talk about and have a general understanding of the whole industry. Second, if a worker wants to do a good job, he must sharpen his tools first. From your level, technically your piano level should be enough, but specific to different environments and different customer needs, you should practice playing freely when facing different groups of people. Third, practice makes perfect. It's definitely good for you to practice the songs that are often played in western restaurants or hotels. In a word, that's basically it. Nothing complicated. Everything depends on people.
