At dawn, 56 salutes have been arranged in two groups of eight figures between Chairman Mao Memorial Hall and Zhengyangmen. The launching task of the salute is more arduous than ever before. In the past, the maximum broadcast was 2 1. This time, 50 rounds, 28 salutes and 56 salutes were broadcast alternately in two groups, and they should keep pace with the national flag guards. This scale, this form and this standard are the first time in China. According to the regulations, before the salute is fired, the salute artillery usually stands 8 meters behind the salute. After hearing the operation command, they ran neatly in place and fired a salute in a stand-at-attention posture.
