What constellation does the injury represent?

The zodiac signs related to injuries are "sheep" and "snake".

The traditional Chinese character of "injury" is "injury", which consists of "person" and "vector". "Arrow" refers to an arrow, and "man" refers to a person, which together means injury, so the zodiac animals related to injury are all animals related to "arrow", namely "sheep" and "snake". In China folklore, sheep are considered to be sensitive and fragile animals, while in Chinese characters, "Si" is homophonic with "snake", so "snake" is also related to "injury".

The above is only to explain the zodiac speculation related to "injury", for reference only.
