Hi. My name is Giang and I'm 10 years old. I live in Hanoi Capital City with my family. I am studying at Thu Le Primary School. I like reading comic books because they are funny and interesting. In my free time, I usually play badminton with my friends. Sometimes, I stay at school to finish my homework. My best friends are Hương, Tú and Đông. They are very friendly and kind.
