Giới thiệu về bản thân
I have a brother younger. His name is Bon. He is seven years old. He has a short black hair and big black eyes. I hate he because he often teases younger children. I like he because he is kind and funny. He always make me smile. I play game with him in the weekend. He is my best friend in my family.
