Why do hotels need English training?

I learned from this teacher the improved teaching method of 1: 1. You can go and see ABC Horizon English. Well, the course is tailor-made for me, and I think it's a good introduction. This kind of study should also provide you with great progress, and I will make great progress. Every place here is different, and the standards of every hotel are different. In Xiamen, it is 000- 10000 yuan. I have a classmate who works in the Kelpolo Hotel, earning more than 10,000 yuan a month. It seems that Kelpolo is not a five-star hotel.
