What are the black beads in the eyes of the zodiac? Black eyes are the zodiac cows.

In the zodiac, everyone knows that cows are color blind and see either black or white. Everything that can be felt is moving, so the matador will hold it in front of the cow with a piece of cloth in order to arouse the fighting spirit of the cow. The cow thought it was attacked, so he rushed to the cloth with all his strength. Both eyes see black, so black eyes are zodiac cows. People who belong to cattle are more introverted and will not have conflicts with others in life. Even if they have ideas, they will keep them in their hearts and will not share them with people around them. They are very enterprising, they will take their work seriously and get promoted quickly.
