Why do you have to put two pairs of chopsticks, one black and one white, in front of everyone when eating in a hotel?

White is a public chopsticks, and black is a private chopsticks. "Double Chopsticks System" means that one person matches two pairs of chopsticks. The two pairs of chopsticks are different in color and have their own division of labor. A pair of eating chopsticks and a pair of eating chopsticks can prevent and reduce the chances of cross-infection of various infectious diseases.

Public chopsticks are public chopsticks, that is, chopsticks used by everyone to hold food. They are put on a plate for everyone to use, but they can't be put in their mouths. They are designed for health problems. Private chopsticks are everyone's own chopsticks. Now everyone advocates using public chopsticks for eating and disinfecting tableware.

The function of using public chopsticks is to prevent possible diseases from spreading from themselves. If three people in a family have hepatitis B, then not everyone needs to use it to cut off the infection, but as long as the hepatitis B patients use it, they can cut off the infection. Therefore, the use of public chopsticks is not to stop others' performances, but to protect others' performances.

From the point of view of public health, Chinese food should be divided into meals like western food, or public chopsticks and spoons should be used. This is not a new topic. Whether it is a gathering of relatives and friends or a family dinner, few people take the initiative to use public chopsticks and spoons. In reality, the dining methods of public chopsticks, public spoons and divided chopsticks are still not popular.
