What was rock and roll as a child?

When I was a child, I played with a rocking car, which is a toy car that needs children or others to generate power to shake. There is also an automatic gear, which will automatically shake when the switch is turned on (most of the streets are coin-operated).

Swing machine, also known as swing machine, rocking car, children's coin swing machine, cradle car, etc. , is a kind of amusement equipment. As the name implies, the rocking machine can rock, but its single-minded rotation is not completely entertaining. The front of the swing machine is equipped with painting screen or LCD animation, dynamic animation, etc. And it is also equipped with MP3, which is accompanied by music when swinging, so that children can enjoy their vision and hearing.
