HI,all.i am come from china, i want to improve my speaking english.nice to meet you.

First notebook entry: Introducing myself

Hello everyone, I am Chinese.  I very much like English, could you please teach me?  My Chinese is very good.

Good to meet you and I would like to practice my putonghua with you as well while you learn from English.

First off, 

You are a chinese guy, not guys unless you are introducing many people. I am assuming this is not the case. 

Corrected. Hello everyone, I am a chinese guy.

Also, be specific with what you like about English. For example

I like learning English very much, will anyone like to teach me?

For proper English you will also want to start your sentence off with capitalizing your words and not using the word "and".
