There were no colorful electronic devices in ancient times. How do children entertain themselves?

Nowadays, children's biggest toys are mobile games. Apart from school hours, the first thing they do when they go home is to play with their mobile phones. Many kindergarten children are fluent in playing mobile phones. As soon as the child cried, the parents quickly gave the child the mobile phone. In ancient times, although there were no mobile phones, there were many forms of entertainment for the post-90s generation, such as going out for a spring outing, riding horses, fighting crickets and playing with mud. There are all kinds of small toys, ringing bells, flying kites and so on. In ancient China, there were four toys: Nine-Chain, Huarong Road, Tangram and Luban Lock. These are all games that can develop children's intelligence and let them learn to think and solve problems independently. Nowadays, the mobile games that children play are nothing more than some brainless games such as fighting and killing, or dressing up. Nine rings is to string them all together with nine rings, and finally remove them one by one. Can be considered a success. Huarong Road is a chess game, and the principle is still unclear. It moves the chess pieces so that they reach the bottom middle of the board, that is, the exit position, but it is stipulated that they cannot cross the chess pieces. With as few steps as possible, because this is to help Cao Cao, we have also set up various obstacles. It is also very laborious. Tangram, as its name implies, is seven boards with different shapes. These seven boards can be matched in many ways to form various shapes. Can spell 1000 at most. Luban Lock was actually created by Luban to test his son. Six pieces of wood are spliced together, so that my son can disassemble these six pieces of wood and assemble them again without tools such as nails. Like father, like son, Luban's son has been solved. In fact, he fixed the batten vertically by biting, but most people should not think of it. Later, this little game spread widely and became one of the four big toys in ancient China. I hope that parents now let their children play with Luban Lock and Nine Chains to cultivate their patience and thinking ability.
