Hello! My name is Thang. Today I would like to introduce myself. I'm a student majoring in Korean studies. I'm learning Korean and English. Now I'm 19 old enough to be independent and I like to watch TV and read books but I prefer reading books to watching TV. I used to read the comic in the cafe and felt like learning many new things. Sometimes I remember reading books, but I forget it. I'm interested in people thinking about me. I spend a day studying and when I have leisure I will watch cartoons. I plan to become a tour guide to go all over the country and also watch all the natural beauty of the country. I wish everything would take place according to my will. I always watch the sky full of stars alone with longing to develop oneself. If I were a bird dove, I would let myself in the wind.
