Không phải điền, chỗ đó bỏ trống

My name is Nguyen Thi Khanh Huyen, Vu Kiet Lower Secondary School, Thuan Thanh district, Bac Ninh province. My family has 6 people: his grandmother, father, mother and my two sisters. His grandmother had retired cadres. Three, my mother were teachers. My brother has a very beautiful name:Nguyen Huu Son

Like his grandfather and father, I love nature. My family's house, though not very large but there is always the green of plants; yellow chrysanthemums, roses scarlet ... he and my father planted in the pot pre veranda, at the corner of my desk next to the window list, my mother hung a royal orchid message, each flower is identical to a lovely yellow butterfly. The front porch is a bird cage with Oriental Magpie-Robin uncle had retired and the song crispy clear.

I respect grandparents, parents and loved my little brother. After a day of work, study, dinner is at my family reunion complete, most crowded. I found in the home and family a source of great motivation in learning and in life.

In class, I have many friends, both male and female. But each one counted, but we play together very close, always unity, respect and help each other. This human exchange meeting, I am very eager to be acquainted with all of you!

Therefore vegetables never have to buy, everyone self-sufficient for your family. Farmers in the countryside you everyone naive, gentle and hardworking. They call each other à á work, calling each other back to the sun as the sun off. Countryside scenery you every morning when it's dark and crowded, bustling. During the wind blows, the little children as kites shambled blur between hot summer afternoon to drop. Kite flying high, the flute acts when the wind blows. The kids in my hometown whom did you look naïve, just like looking at things on the fly so high. Perhaps that is the dream of flying high in the future.
