The event is scheduled for Saturday from 4:00 p.m. to 5:20 p.m. When everyone arrives, we will hand out fluorescent wristbands to everyone and use Amap location sharing for positioning. After changing the designated profile picture, the mouse began to hide for five minutes, and then the cat moved to catch the mouse. The captured mouse turns into a cat until all the mice are captured or the countdown ends, with the cat winning and the mouse winning respectively. The cat with the most catches wins the title of "Elvis" and sings an Elvis song for everyone.
