and

1. No age.

Ask clients about their age, especially women.

Nor do you want to inquire about his age elsewhere.

2. No marriage.

Marriage is purely personal. It is impolite to ask others for information.

It is even more inappropriate to ask about the marital status of the opposite sex.

3, do not ask for income

To some extent, income is related to personal ability and status. It is a person's face.

Income related housing, property and so on should not be discussed.

4, do not ask the address.

Unless you want to visit a client's home (that depends on whether or not you are invited), do not ask the customer's address.

5. No questions.

Personal experience is a person's card, and even privacy, so do not ask the customer's experience.

6, do not ask faith

Religious beliefs and political opinions are very serious.

7, do not ask the body.

Do not ask the customer's weight, not to say that he is fatter than others.

You can't ask others if they have cosmetic surgery, do they wear dentures or wig.
