Old-time comics were "put down" performances, and in the early years of the People's Republic of China, individual outstanding comics were invited into the "garden", this period of time, comics bowed on stage first (thank you for the food and clothing parents to support the show), and then bowed again when he went down to bow (thank you for the show). The first bow was made when the comedian went on stage, and the second bow was made when he came off stage (to thank his parents for their support).
In individual segments, the phrase "bowing on stage and bowing off stage" (a linguistic expression) was added as a "gimmick" for the sake of the plot.
However, the verbal expression "bowing on stage and bowing off stage" is not a fixed formula for all the old time comedy segments. It is currently used by individual traditional segments and TW comedians.
