There are mainly the following three aspects: first, improve personal quality: the personal quality of business people is a kind of personal cultivation and its performance. Don't make noise in public unless you smoke in front of outsiders. Second, it helps to establish good interpersonal communication: for example, the secretary answers the phone to find the boss, first tells the other party that the person he is looking for is not in, and then asks who the other party is and what can I do for you. Make an appointment to visit others, be punctual and keep the appointment, and arrive ahead of time for arrangements or ongoing matters that may affect others. 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 unknown things is to follow or imitate, with static braking. For example, this is the first time that the hostess has taken a seat at a western-style banquet. The hostess's napkin indicates the beginning of the banquet, and the hostess can only eat it if she picks up the knife and fork. The hostess put the napkin on the table to signal the end of the party.
