First notebook entry: Introducing myself

Hi, I am Chinese and I want to to improve my English in both writing and speaking.  English is used in our daily life.  I need to practice because I love it and I want to find a better job. On the other hand, my mother tongue is mandarin Chinese and I am so glad to help you with learning it.

I am a college student and I also work in a Company as an HR Assistant, and I hope we can find common topics, and finally, thank you for checking my introduction!

Good, a bone of contention may be that I used an before HR. For sure 'a Human Resources Assistant.' But, 'an HR Assistant' sounds nicer to me.
