I think you mean, "would you be willing to design a language course for your language partners?", 对吧？There are many good English courses online. Many of them are designed for Chinese speakers. I would be happy to help you choose one, and I would be happy to give you my honest opinion of your language level. I am not an English teacher, but I have been learning languages for a long time.

I don't think any of us can understand your question—what do you want to know?

design means creativety . creativety is your own property .
