According to Netease, flag signing at music festivals usually refers to the flag used to represent or identify a specific band, singer or musical performance at music festivals or other musical activities. These flags are usually made by organizers or fans and hung or waved at music festivals to show their support and love for specific bands or singers. Music festival flags can be of any shape and size, and are usually made of lightweight materials, such as cloth, paper or plastic. They can be decorated with band or singer's logo, name, album cover or other related patterns to increase visual effect and recognition. In music festivals, flag signing can be a prop for an active atmosphere, allowing fans to express their enthusiasm and loyalty. At the same time, signing the flag can also add color and visual impact to the music festival and create a more warm and cheerful atmosphere.
