Dance upon hearing the rooster, originally meant to get up and dance with the sword upon hearing the crowing of the rooster. Later, it was used as a metaphor for those who are determined to serve the country and immediately rise up. "Book of Jin·Zu Ti Biography" records: It is said that Zu Ti, a general in the Eastern Jin Dynasty, was very ambitious when he was young. Every time he discussed the current situation with his friend Liu Kun, he was always impassioned and full of righteous indignation. In order to serve the country, they listened in the middle of the night. When the rooster crows, he puts on his clothes and gets up, draws his sword and practices martial arts, and exercises hard.
