I want to work in Shangri-La Hotel, but I don't know how to improve my ability.

Sister, I have been in a five-star hotel for more than 1 years, so I can understand your psychology now. But the hotel industry is not as brilliant and hard as you think. Are you ready to face the cruel reality? Don't be completely moved by one lecture, you need to know more than the superficial things. As it happens, I am in Dalian, and I may be able to help you one or two. Don't think so hard about English, you just lack an environment. You need the courage to open your mouth and listen. Otherwise, even if you learn literally well, you will stutter when you express yourself in English, and even if you take CET-6, you won't pass the interview. And about the interview, what position do you want to apply for? This determines whether your qualifications can be successfully applied for.
