Peking Opera, a traditional opera art in China, has developed into a national quintessence. On this stage, many characters are endowed with special symbolic meanings. Among them, the role with four flags behind it is the most common and one of the most representative roles. This kind of flag is generally called "leaning on the flag", followed by characters with four flags, usually accompanied by firecrackers, which also reflects their attention and love for this performing art form.

The setting of "leaning on the flag" is often related to the background. They are usually portrayed as heroes, just and loyal, representing a kind of spirit and belief. In Beijing opera, the standard bearers are usually those who protect the country, the nation and the people. Their duty is to protect villages, cities, countries and people and safeguard peace and justice. Their images often represent China's excellent traditional cultural values, such as loyalty, justice, courage and kindness.

The origin of Beijing opera martial arts students relying on flags;

Relying on the flag originated from the ancient general's order flag. When the ancient generals gave the order, they usually held the flag in one hand and held the reins in the other, and galloped on horseback. When the speed is fast or the road is uneven, you need to hold the reins with both hands to keep your body balanced, so that the flag is inserted on your waist. Lingqi evolved into a flag, from one side to all sides, from being inserted in the waist to being fixed on the back. Although he lost his command function, he retained his status as a general.

Actors can rely on static and dynamic flags to express the joys and sorrows of characters on many levels. Even if you stand still, add three points to your handsomeness. Once the flag swings from side to side and flies up and down, it fully shows the fierce atmosphere of the war and mobilizes the emotions of the audience.
