Planning to move to china 2025

Hi,

I have several questions regarding moving to China and also increasing my earnings when I arrive,

I have tutoring and evening experience teaching ESL Students teaching English. I have my TEFL and undergraduate degree, and I am British and white.

I am considering moving to a Tier 1 city in China and taking a trip to see the cities in March "025 to decide on my preference and to get a feeling for them.

I am considering the following cities. Beijing, Shenzhen, Shanghai, and Chongqing.

What salary should I expect, and what is the accommodation cost in these cities? If anyone knows a recruiter for each, that would help me understand the offers in that city, as I don't really know how to discount them until I make the final choice! Sorry for the open-ended questions!
