There are two meanings for girls to send the correct Tai Chi to boys. One is to make a move, asking the other party to take it and launch a conversation offensive. Everyone can put it down and chat to enhance understanding; Second, girls are bored and curious, and they send each other away with a casual expression. If boys are interested, they can go back to the correct Tai Chi, take the initiative to attack and communicate further. If they are not interested, then everyone will play Tai Chi with each other. You push me to block, you advance and I retreat, avoiding or shifting sensitive topics.
