Creative background

In 1971, in order to prepare for the Asian Table Tennis Friendly Tournament held in Beijing, relevant departments requested the Chinese People’s Liberation Army Military Orchestra to compose A "Athletes' March". Within a few days, seven or eight comrades had the single melody score of "Athletes' March". After careful consideration, everyone agreed that the main melody written by amateur creator Wu Guangrui was good, but it still needed further processing.

The leadership decided to send professional creators Jia Di and Wu Guangrui to complete this glorious task. In order to write "Athletes' March", Wu Guangrui watched their sports competitions with the athletes many times, read relevant sports materials, and repeatedly listened to some famous marches at home and abroad. After the labor of Wu Guangrui and other comrades, this "Athletes' March" was finally born.
