Great introduction Ivy. I have made some minor corrections and additions. Use of punctuation marks is quite important in English language. Compare my response to yours and you will notice the difference. 

"Hi. My name is Ivy. I'm very glad to meet you. I come from Qujing in Yunnan Province, China. In my opinion Qujing is a beautiful city. It has a nice climate and no traffic jams. Well I think I should talk something about myself. I love to travel and play outdoor sports. Just like other girls I also like music, snacks and all good things.

I graduated from Sanming College. When I passed the CECT4 I stopped learning English. So now my English is very poor. I hope I can brush up on my English language skills. I think the best way to practice a language is to talk with others so I have come here on italki. Look forward to working with you friends!"
