There is a little game about unity.

We once played one during pre-job training. It doesn't matter if the name is not important. We call it driving a train. The specific rule is to prepare two thick planks with a width of 20 cm, nail big nails at regular intervals on both sides of the planks, and tie thick ropes. Players who play games put their feet on the two planks respectively, hold the ropes in their hands, and move forward together. This is very difficult. You are allowed to shout slogans when you do it the first time, and no one is allowed to make any noise when you finish it the second time.

There is also a blind man building a house, giving two ropes of different lengths and putting triangles and squares on the ground respectively, but only if everyone covers his eyes. The game should be planned in advance before the action, and it is necessary to make sure that there is only one person in command. The captain must listen carefully to other people's opinions, otherwise it will be chaotic.
