Dear Xiaohua:
I’m very glad to receive your letter. From your letter, I know you have shown   great interest in inventing new things. That’s great. As for how to be an inventor, there is no quick answer to     .
Coming from different cultures and having different backgrounds, inventors do not seem to have much     common. But creative thinking,     is greatly valued, is perhaps the basic skill an inventor should have. In order to explore new possibilities, you will have to learn to break    from old thought patterns. When you get stuck, try to look at the problem in    many ways as possible. Each new   may improve your understanding.
More importantly, always keep it in your mind    success is no accident. It is the result of a long process of trial and error. Above all, the main task for you is to study hard and try to learn more knowledge. This, of course, will lay a solid foundation.
Hope your future invention will make a difference.
Good luck.

Wang Li
