The most commonly used form of address in China is "comrade", regardless of occupation, age and status.

In the workplace or related occasions, the intelligentsia can directly call a professional title or name before the title, such as the king.

For men, "Sir" is more appropriate for ladies to call "Miss" or "madam".

Among ordinary colleagues, you can call "old X" and "small X".

People who are more closely related may be called by their names instead of their surnames.

We should pay attention to the following points when using address.

(1) to call teachers or elders to use "you" instead of "you", you must not call it by name.

(2) the first time you meet or not meet, you should use "you" instead of "you" to show modesty and respect.

(3) don't call "acquaintance" when you meet your acquaintance, so as not to give people a sense of being rusty and reserved.
