Today is November 20, I and my friends are walking on a familiar path filled with brilliant sunlight, please let them out. The deep birds tumbled across the branches as if sharing joy with us. She entered the schoolyard gate which was filled with flags and flowers. Everywhere resounded the laughter of students. Everyone wears white shirts, blue pants are beautiful. Blue and white look intertwined like fluttering, butterfly wings. Above the flagpole is the words "Celebration of Vietnamese Teachers' Day", prominent against the deep blue background. Under the stands is a row of chairs where the teachers sit. The most beautiful flowers were placed in a vase on the delegate table. In the bustling atmosphere, suddenly the school drum rang "Tung! ... Tung! ... Tung ...". The principal, the old father of the whole school, whose hair was gray for years, the figure of bones and bones stepped onto the stage, his warm voice said: "Children! You know? A good lesson for the students, how much effort the teachers have to spend, sometimes staying up all night to have a good lesson. Rainy days, cold winds, muddy roads, teachers live It was very far away, but still arrived on time. The teachers did it for the sake of the children. Everyone wanted them to study well, diligently to become useful people for the country, so they must study hard and be obedient. ". The principal's words just ended, a round of applause rose. We all told ourselves that we should try to be obedient in order not to betray our teachers' expectations.
