If you are sick, you should go to a regular hospital for regular doctor treatment. Don't trust the so-called expert teacher on WeChat. 99.99% are liars. The "gastrointestinal consultant-Teacher Li" mentioned upstairs is a fraud gang. I deliberately added his threat signal, and he kept pushing his medicine for 7 days 1000 or so. I was hacked when I said I was a gastroenterologist.
