What are the rules of the game in fish begins to stink at the head?

All the staff are divided into two teams, and the person or thing to be pinched is decided by drawing lots. Except for the first person and the enemy who can see the drawings, everyone else wears an eye mask to pinch plasticine in the way of solitaire. The last person guesses the answer according to the image squeezed by the previous person, and gets extra points for answering one correctly. After two rounds of competition, the loser will be punished by bitter tea.
