Notebook1_How do I know this site? From today, I try to write notebook every day. Begin with notebook1_how do I know this site? By a chance, I met a teacher in another exchange language website. He wanted to learn Vietnamese. In that time, I was free and also wanted to learn English. We exchanged language with each other. I taught him Vietnamese and he taught me English. He said with me he taught English on this site and suggest me teach Vietnamese. He helped and guided me how to create profile and how to teach. Actually, I didn't believe I can teach, but i did. I was happy when introduce my language to foreigner. I was happy when they can talk my language. Some of them want to learn Vietnamese to travel. I also like travel. I think try to taste new food when travel well get more experience. So I introduce Vietnamese foods to them. I hope they can eat Vietnamese food when they travel on my beautiful country.
