It is embodied in three aspects:

1, improve personal quality

2, help to establish good interpersonal communication.

3. Maintain personal and corporate image.

The most basic function of business etiquette is "disaster reduction effect": less making a fool of yourself, less losing face, less damaging interpersonal relationships, and the safest way to meet something you don't know is to follow or imitate, with static braking. For example, the hostess attended a western-style banquet for the first time. Only the hostess can sit down, and others can sit down. The hostess picked up a napkin to indicate the start of the banquet, and the hostess picked up a knife and fork for others to eat. The hostess put the napkin on the table to signal the end of the party.
