How much has the ESL industry in China changed since COVID?

I recently made a post asking how much China has changed since COVID and got a lot of great answers. Now I`d like to know specifically about teaching ESL in China and how the industry has changed in the past five years. Obviously the double reduction policy has decreased the amount of training center jobs available and the requirements for teachers is much stricter now, but how else has it changed? Is it better, worse or pretty much the same as before?

Thanks.
