The so-called "payment" usually means that non-payment, non-payment or refusal to pay all constitute light or heavy illegal acts. If we analyze the ancient meaning of the word "salary", it is somewhat similar to the word "ban" in "ban". It is a mandatory document issued by the ancient government and must be unconditionally implemented by lower levels.

In the final analysis, whether it is tap water, electricity or gas, the word "payment" is used because they all have the special nature of using first and paying later.
