Hi, I want to teach English in china but I’m new to this, and I have not taught before. Please help me out here:

Not so good things about me:
- I don’t have a teaching degree.
- I’m fluent in English, but my grammar is 7/10.

Good things:
- I know some Mandarin.
- I’m good with children.
- I’m working on a TESL certification.

My Education..so far:
- Diploma in Webdesign/development
- Diploma in E-commerce

Is it worth getting a teaching degree? I’m 20 years old.

Any help, suggestions would be a lot of help. Thanks
