A few children can play the game of "turning on and off the lights" with little activity in the yard after dinner.

　　Everyone stood in the yard, and after hearing the signal of "turning off the lights", they immediately walked up, freely chose a companion, and whispered about their respective roles and actions, and prepared to make a combination shape together.

　　When the signal of "turning on the light" is sent, groups of children make the shapes and stay where they are.

　　Waiting for the hair to make people look around and ask one by one: what is your styling name? Or what action are you doing?

　　Children answer according to their own actions, such as "Cats catch mice", "Eagles catch chickens", "Transformers" or "water lilies blossom".

　　The game method of turning on and off the lights is to have a button, which can be pressed to turn off the lights.
