My family há 5 members: my family, my mother, my sister , me and young sister. My mother and my father are worker and thay are 34 years old. My sister and me are students, my sister 15 years old. And my young sister is 2 years old. My house has 9 rooms: 2 living room, 3 bedroom , 2 bathroom and 2 kitchen. Although 9 rooms in my house are wonderful, but i love my bedroom best.In my bedroom, there  are a table in front of the big window. I love my family very much because my family brings fun for me when i am tired or  sad.
