The history of photography is not very long, but the memories left by photos are beautiful and meaningful, but Chinese don't like photography for simple and ridiculous reasons. Because in the past people did not understand the principle of photography, very early camera is a large box, below is a tripod, the box is connected to a leather tube, there is a leather ball on the head of the tube, when taking pictures, the staff pinch the ball with their hands, after the photo will give you photos and negatives, the negatives are red, so some people spread that the photograph is to draw human blood, saying that there is a goblin in the box, the goblin will draw your blood, and people will get sick. So there are a lot of people who don't take pictures.
