1, called, is a kind of wota art. In China, it refers to a spontaneous behavior that the audience under the stage follows the rhythm of music and interacts with the performers on the stage by shouting and waving light sticks according to certain rules. In Japan, call simply means shouting slogans according to the elements in the lyrics of songs in Idol Live, including following the lyrics, singing and responding.

Calling is a concentrated expression of support and love for artists on the stage. Seemingly crazy, but actually rational, mainly reflected in the uniform shouts and a sea of light sticks under the stage.

Now it means to do something for the active atmosphere and cheer for someone.

Eating chicken represents good luck, and eating chicken at night is a popular word on the Internet. This word first came from the movie Win 2 1, and later spread all over the Internet in the game Survival of the Jedi: The Great Escape. When you win the first prize, there will be a line: "Good luck, eat chicken tonight". So "eating chicken" means that the player is there.

I hope it helps you!
