Hello Sharon! You're English is very good! Much better than my Chinese. 

A lot of the little corrections I made could be done in different ways. There are several different ways that they could have been corrected, but I tried to add some things that would make the sentances flow well. But again, your English is already very good! :D

First notebook entry: Introducing myself

Hello everyone, I'm Sharon, and my native language is Chinese. Now I live in Beijing, China. Well, I was not born in Beijing but in Zhengzhou in Henan province. I grew up in the countryside in Zhengzhou and so I love nature. I have worked in a US company, so I'd like to improve my English for better career development and also to make friends from different countries. In my spare time, I love sports (especially Yoga), music, reading, and watching US TV. I had been doing Yoga for seven months last year. It was a great help for my health. I hope I can keep doing it.
