What is Xiao Yin's zodiac sign? Which of the twelve constellations is Xiao Yin?

Xiao Yin refers to the snakes, horses, sheep, monkeys, chickens, dogs and pigs in the Chinese zodiac. These seven constellations are called Xiao Yin because their constellation attributes are opposite to the orbit of the sun, that is, their birth years are opposite to the orbit of the sun. For example, the sun runs from childhood to ugliness, and the cloudy year is at noon, which is contrary to the trajectory of the sun.
