    Many of you must have watched the celebration in Tian' anmen Square on TV on Oct 1. But only some lucky Beijing students got the chance to take part in the celebration themselves!

Chen Zehao, 14, is a student from Beijing's Chenjinglun High School. He performed in one of the 36 formations（方阵）in the mass parade （群众游行）. “I'll never forget when groups of aircraft （飞机） flew above my head and made a 70 in the air,” Chen said. “I was full of joy and pride.”

Twin brothers Ma Congyuan and Ma Conglin performed in a choir（合唱团）. The 15-year-olds are from Beijing No.4 High School. The choir was made up of 1,400 students from universities, high schools and primary schools in Beijing. They performed 16 songs, including My Motherland and Me and On the Hopeful Field.

“The beautiful fireworks, the strong sound of thousands of people singing together, and the bright symphonic（交响乐的）music. All these are still in my ears. It has been a great honor to be part of such a great event!” Ma Congyuan said.
