你有一些语法错误哦，而且也不流利。我帮你修正吧。（我也是个中国学生）

I come from China and I am a student.I hope to, with this platform, make friends  from all over the  world, learn their languages and understand different cultures. My Chinese is average and my English is not too bad. If you are interested Chinese or culture of China, welcome to add me to your partners' list, I hope we can be good friends.
