1. The main principle of shaking hands is to respect others. The procedure of shaking hands should be determined according to the social status, age, gender and the identity of the guest and the host, and generally follow the principle of "honour person decides".

2. The basic etiquette of shaking hands is: when shaking hands, eyes should be fixed on each other, and smile or say hello. Among friends of the same age, when meeting each other, make a gesture of respect first; Between elders and juniors, between superiors and subordinates, the former should reach out first, and the latter should greet first. After the former reaches out, the latter can reach out and shake hands. Between a man and a woman, the man can only reach out and shake hands after the woman reaches out. If the woman has no intention of shaking hands, the man can nod or bow. If the man is an ancestor, it is also appropriate for the man to reach out first; Between the host and the guest, the host should reach out first, and the guest should reach out and shake hands, but when the guest says goodbye, the guest should reach out and say goodbye first, and the host can shake hands and say goodbye. If you want to shake hands with many people, you should give priority to the same sex before the opposite sex, the elder before the younger generation, the higher position before the lower position, and the married before the unmarried, that is, the so-called superior priority, the elder priority, the master priority and the lady priority. When receiving foreign guests, the host has the obligation to reach out to the guests first. No matter whether the other party is male or female, the host should reach out first to show his welcome.

3. In social and business situations, when others have reached out their hands out of order, they should immediately return them without hesitation. It is impolite to refuse others' handshakes. Therefore, the most polite order should be: first superior, then subordinate, first elder, then junior, first host, then guest.
