When I was a child, I drew a few squares with stones and then jumped a few squares. What's the name of this game? How to play?

Hopping house, also called jumping airplane, is a worldwide children's game and one of the traditional folk sports games in China. It is very interesting and entertaining, and has always been loved by children. It was quite common in the 1950s and 1980s, and some children's playgrounds, parks and primary school playgrounds all had hopscotch places. Sometimes even in an open space, as long as there is a piece of chalk or a branch, the children will draw nine "hopscotch" squares on the ground and then play together.
