What do you mean by seven kills?

According to the feudal laws of China, there are seven kinds of homicide, including murder, manslaughter, robbery, fighting, manslaughter, drama and negligence, which are collectively called seven killings.

Seven kills is one of the top ten gods, also known as Pianguan. Two yang and two yin are equal, but there are differences between two men and two women. Because they don't live together, they are called partial officials. Because they are separated by seven places and fight with each other, they are called seven kills.

Seven kills refers to the lonely star, which is very fierce, cruel and unlucky.
