It's the first day on italki This afternoon, I have visited this website for the first time. I think the website is so cool because I can make friends from the whole world. And I can write an brief essay on it and there may be someone who will correct the grammar mistakes or expression irregularities for me. (Perhaps you who is reading this now is the one who will help me to correct the wrong expressions.Thank you! ) For another side, I can also help the people who are now studying Chinese, which is my mother tongue. Maybe just correct the composition like I've done just now. By the way, is the word "correct" right or not here? Well, all in all, a nice discovery!
