On some dining tables, there will be two pairs of chopsticks, one black and one white, so how to distinguish which color to make public chopsticks? What are the allusions?

Light-colored chopsticks are mostly used as public chopsticks, and there are no allusions.

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.

Extended data:

The concept of separate meals system was put forward 20 years ago, but it will take time to implement it widely. On the one hand, restaurants should take the initiative to establish a sense of sharing meals and provide guests with common spoons and chopsticks. On the other hand, guests should also supervise the sharing system of the catering industry and take the initiative to ask for sharing meals.

There are three main forms of dining system: chef dining, waiter dining and diners dining by themselves. Among these three forms of meal sharing, chef's meal sharing and waiter's meal sharing are easier to be popularized in large restaurants with economic strength.

But for the majority of small and medium-sized restaurants, these two methods will increase the cost of tableware and personnel, which is difficult to promote. Providing public chopsticks and spoons is an acceptable and practical way for both consumers and operators, and should be vigorously promoted.
