What does that gesture mean? Just stick out your index finger and little finger.

In most European countries, people will stretch their arms forward, and then stretch out their index fingers and little fingers to make horns to show that they want to protect themselves from monsters. In some African countries, if this gesture is aimed at someone, it means to make that person unlucky. In many countries in Latin America, the hand with the index finger and the little finger erected indicates "good luck". But in Italy, this gesture means that the wife is having an affair.

Sign language:

Commonly known as "sign language" and "gesture". Sign language is a way to express thoughts and communicate through hand movements and facial expressions.

There are many movements of upper limbs and body when using, and there are two types of expression systems:

(1) does not completely follow the linguistic rules of spoken language, and the expression process is not in strict order.

(2) Fully follow the grammatical rules of spoken language, and the expression process is consistent with spoken and written language. Because of the limited expressive power of hands, the concept of expression is not as accurate as that of audio language, and it is difficult to express abstract ideas.

In deaf education, it should be combined with other language forms.
