Everyone reaches out the index finger of his left hand, then reaches out his right hand to hold the index finger of the next person's left hand, and so on, and finally forms a circle. Then the host said a paragraph (prepared by himself), explaining that every time a specific word is said in this sentence, students will draw out their left index finger and grab the next person's left index finger with their right hand. This game is an ice-breaking game, which can make everyone relax and feel good. You can try.
