Male chopsticks are chopsticks specially used for holding vegetables. Not for eating. Sometimes, for the convenience of picking vegetables, each person has a pair. Many people mistakenly think that using public chopsticks is to prevent others from infecting themselves with diseases. In fact, this is a misunderstanding. The biggest function of using public chopsticks is to prevent possible diseases from spreading from yourself. For example, if someone in a family of three has Helicobacter pylori, then not everyone needs to use it to cut off the infection, but as long as the patient uses it, the infection can be cut off. Therefore, the use of public chopsticks is not to prevent the performance of others, but to protect the performance of others.

"White is a public chopstick, and black is a private chopstick. (Those near the plate are black, and those far from the plate are white.). One person has two pairs of chopsticks, two pairs of chopsticks with different colors, each with a division of labor, one pair of eating chopsticks and one pair of eating chopsticks, which can prevent and reduce the chance of cross-infection of various infectious diseases.
