In fact, the bull used in bullfighting is color-blind, so no matter what color cloth you show in front of it, the bullfighting has no feeling, and only the shaking objects can arouse its fighting spirit (it has been rumored that the red side of the red and yellow cloak in the matador's hand is used to anger the bull and the yellow side is used to calm the bull, which has not been verified).

Characteristics of cattle
The common feature of cattle is that they are strong; Have legs suitable for long-distance running; There are four toes on the foot, but the lateral toes are more degraded than deer, which is suitable for running; The front teeth and canine teeth have degenerated, but the lower front teeth are still preserved. The lower canine teeth are Yemeni teeth. Three pairs of front teeth are inclined forward and shovel-shaped. Because they feed on hard plants, premolars and molars are high crowns, and the enamel is wrinkled.
After the crown is worn, complex tooth patterns are formed on the surface, which is suitable for grazing. In order to store forage and avoid enemies, their stomachs have evolved into four chambers: rumen, honeycomb stomach, flap stomach and glandular stomach, and they also have the habit of "ruminating" in order to better digest and absorb food.
