On November 20, my school held a musical performance to celebrate Vietnamese Teachers' Day. That day, at 7:30 a.m., students from the whole school were present. The teachers wear traditional Vietnamese ao dai. And the students wearing uniforms look so cute. First, the Principal gave the opening speech. Followed by special musical performances: blood, singing, story-telling, poetry reading and violin. Your violin performance Lan, my class, is the best. You play Merry Christmas. The sound of the piano rose, sometimes low and sometimes high, the whole school silently listened as if hypnotized. The sound of the piano had just stopped and applause broke out. Some of the fifth graders even stood up and shouted: “Let's play more! Play more!
