Male chopsticks are chopsticks specially used to hold 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. Actually, this is a misunderstanding. The biggest function of using public chopsticks is to prevent possible diseases from spreading from oneself. For example, if someone in a family of three has Helicobacter pylori, 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 stop others' performances, but to protect others' performances.
