Excuse me, does the British hotel include accommodation? What is the monthly salary if it is included? if I ... ...

I used to work in a hotel, but later I switched to continue my studies. I'm studying for a doctorate now.

To answer your question:

Hotels don't include food and accommodation, and only a few large enterprises occasionally encounter food and accommodation. Anyone who doesn't finish breakfast can get a point, without proper management.

This is very difficult. Why do you want to check the requirements of Tier 2 visa in the UK?

British hotels generally prefer people who have graduated from local universities, and will not consider international employees (foreigners), especially those who have obtained degrees in China.

At present, the Tier2 visa control in the UK is very strict. Even if the NQF skill level is lower than level 6, even the enterprise-guaranteed visa cannot be over-signed. You can check UKVI for details.
