Deaf college students are ambitious to start a business. I support you very much. I wish you success first!

I think, as long as there is no requirement for listening, the door is open to you. For example,

Start a website and take on the job of website design. If you are not a professional, you can join a few friends who know art and IT to start this website design company.

Or open a store on Taobao to sell things

Set up a sign language teaching company to provide paid teaching for parents in need.

I didn't think of any more at the moment. I'll come here to supplement it when I do.
