What does it mean to like the gesture upside down?

What is the difference between Chinese and foreign gestures? Gesture is a kind of body language. Gestures have different meanings in different countries and regions. When using gestures to represent numbers, China people hold out their forefinger to indicate "1", and Europeans and Americans hold out their thumbs to indicate "1"; China people hold out their forefinger and middle finger to indicate "2", Europeans and Americans hold out their thumb and forefinger to indicate "2", and then hold out their middle finger, ring finger and little finger to indicate "3", "4" and "5" in turn. In China, the five fingers of one hand can also represent the number from 6 to 10, while in Europe and America, the number from 6 to 10 needs two hands to represent it, such as separating the five fingers of one hand, adding up the thumb of the other hand to be "6", and so on. In China, before the festival, the forefinger is bent to indicate "9", but the Japanese use this gesture to indicate "stealing". In China, the gesture of "10" means making a fist with the right hand, while in Britain and the United States, it means "good luck" or close relationship with someone. Stretch out a hand and draw a circle with your index finger and thumb. Americans use this gesture to mean "OK", which means "praise and promise". In India, it means "correct"; In Thailand, it means "no problem"; In Japan, Myanmar and South Korea, it means "money"; In France, it means "insignificant" or "worthless"; Buddhists in Sri Lanka make the same gesture with their right hand, put it on their chin and chest, and slightly lean over their heads to express their hope that the other party will "take care"; In Brazil, Greece and Sardinia, Italy, this is a disgusting and filthy gesture; In Malta, this is a silent and vicious swear word. When people in China express their gratitude, they often put their thumbs up straight and the other four fingers curl up; A thumbs-up is a sign of contempt. The Japanese use the thumb to mean "old man" and the little finger to mean "lover". In Britain, giving a thumbs-up means asking for a ride. In Britain and America, V-shaped gestures are used to indicate "victory" and "success"; In Asian and African countries, V-shaped gestures generally mean two or two meanings. In Europe, people are used to greeting with their hands. The formal way is to extend your arms, palms outward, and swing your fingers up and down. Americans shake their whole hand when greeting. In Europe, shaking your whole hand means "no" or "no". In Greece, a person waving his whole hand is an insult to others and will cause unnecessary trouble. In short, when we communicate with people from different countries, regions and nationalities, we need to know their gesture language to avoid jokes and misunderstandings.
