Why do you say "a cow is good, a nest is good, a cow is good, and a slope is good?"

As the name implies, cattle are born with heredity. In the animal kingdom, only the strong are worthy of females. Therefore, when the bull is strong, several cows can mate with it. It's not racial discrimination. Like black Americans now, they are basically very strong. (At that time, when it was shipped to the ship, all the sick people were eliminated. )
