H1B non-compete

I apologize again for the grammatical error. I like this forum very much, but I don’t speak Chinese, so I’m using Google Translate

For H1B, if I have a 120-day non-compete and sign another offer, will I lose my visa?

Someone on the Internet said that I can transfer my H1B. But does this mean that I will work legally for 120 days between two jobs? Or can I never change jobs?

Does anyone have experience with this?

Thank you!
