The idiom "to dance on hearing the rooster" originated from the story of Zu Ti, an ancient Chinese general. Zu Ti was a general at the end of the Han Dynasty. He heard a chicken being disturbed by the enemy's cry in a war, so he immediately got up and led the army to fight back and finally won. This story had been passed down to this day and became an allusion to dancing at the sound of the rooster. Later, this idiom was also used to describe people who could quickly cheer up and move forward in the face of difficulties.
