Introducing myself!

Hello everyone!
My name is Henri and I'm French. I started using Italki very recently, and I find the idea so cool! The opportunity to talk to people from all around the world is really interesting. By the way, I'd like to improve both my English and Chinese, speaking and writing. 

It has been two years that I stopped having english classes, so I think Italki will help me keep up my English level.

I have Chinese origins, that's why I can speak Cantonese (not very well, but I manage). I've watched a lot of Hong Kong dramas haha, so my Cantonese comprehension is quite good. I also learned Mandarin when I was younger, I started when I was seven, but I stopped two years ago.

Thank you for reading me. If you don't mind correcting my mistakes, it would be very kind of you! (Isn't this expression too formal? xD)

(Perhaps a tad (little) formal, depending on what you're going for. You could also use "it would be much appreciated", "it would be a big help", "it would be very nice of you", or you can leave it as is because it sounds nice that way too.)
