Qixi Valentine's Day party

Four lucky families were randomly selected from the field staff. Each family selected one person to suck the table tennis ball from one place to another with a straw, one person to hold the table tennis ball with his hands, and the last person to hold the tray or basket to hold the table tennis ball. The family who sucked the most is the winner. The competition is divided into two rounds, with four households in each round. The winner can get the Most Attractive Award.
