Golf & Mike visited the orphanage and entertained the orphans.
The dance here is the dance used at the school/university freshmen reception party. Seniors will force all the freshmen to dance weirdly and this "Kai Yang" (Roasted Chicken) song is one of the songs used there.
The song says "The chicken is roasted. The chicken is roasted. It's gonna be skewed by a skewer. It's gonna be skew by a skewer. To the left bottom. To the right bottom. It's really hot. It's really hot. It's really hot."
