What number does shaking your head and not shaking your fan represent?

The method of using body language to represent numbers has existed since ancient times, and it is mostly used in teaching and speech, especially in the environment with poor visual effect, such as darkroom. Replacing numbers with body language can make you remember more clearly.

Shaking your head means zero, shaking your fan means one, putting your hand on your head means two, raising your hand means three, putting your hand down means four, putting your hand on your knee means five, putting your hand on your waist means six, putting your hand on your shoulder means seven, raising your hand means eight and putting your hand on your knee means nine. This method of expressing numbers by body language is also called "sign language numbers".

Although sign language numbers are only one method, they can play an important role in some special cases. For example, in places where there is no light or sound, sign language numbers can replace numbers, which is more convenient and reliable.
