Draw the characters one by one, then stack them together and turn the pages quickly. The characters seem to move. What's the name of that cartoon?

This cartoon drawing is called book-turning animation, also called hand-turning animation, paper-turning animation and so on.

It refers to a booklet with several cartoon pictures moving continuously, which gives people a feeling that the pictures are moving because of the persistence of human vision. It can also be said to be an animation technology.

Extended data:

Book-flipping animation is essentially the most primitive animation, and when drawing animation, we will flip the animation paper up and down in a similar way to check the fluency of each animation. However, there are some similar toys on the market. Some people just draw them one by one and tie them up because of interest, or animation learners put pictures in notebooks to understand the difference between different actions.
