As the rules of international civilization, the "civilization line" and "moral line" were introduced to China in the mid-1990s. According to an American anthropologist's research report on human society, the distance between friends and acquaintances is between 45- 120 cm, while the general social distance is around 120-2 10 cm, which makes people most comfortable. However, in life, people ignore the distance of one meter, whether at the front desk of the bank, the day before the airport or the payment window of the hospital. Even if there are compulsory isolation measures, they can't stop them from occupying other people's comfortable space.

Public order involves everyone's interests, so people should learn to say "no" to those who don't follow the "one-meter line" rule, and form an atmosphere in which everyone follows the "one-meter line" rule, so that the "one-meter line" can be truly engraved in people's hearts; Dagong * * places should also set up one-meter stickers, one-meter railings or slogans for places involving the protection of public privacy.
