Great response Rashel. Great ideas and thoughts. But a few grammatical and spelling errors. Consider the following:

"Hello everyone. My name is Rachel. I am a university student from China. I come to italki.com to make friends and meet people from around the world and to learn and improve each other's English and Chinese language skills. I love foreign languages and English is my first language. I want to learn it in the best possible way. Although lot of Chinese students study English but their communicative skills are not very sufficient and they are generally not very fluent in the language. So I would like to interact with people who have good English and are interested in learning Chinese. We can help and assist each other in our learning. Thank you. Goodbye."

Compare it with your response and try to identify errors. Hope it helps in your learning. Feel free to contact me. Regards.
