There is a saying called "crazy as a rabbit in March", which is about rabbits becoming crazy in early spring. At that time, male rabbits fought fiercely with each other to pair with female rabbits.
At the same time, the female rabbits often refuse the male rabbits again and again before giving in to the male rabbits, which makes the pairing behavior look like a crazy dance. This scene makes early observers think that the arrival of spring makes the rabbits crazy. Rabbits and hares belong to the family Rabbinidae, and they breed rapidly. A female can conceive a second litter of rabbits at the same time as the first litter of rabbits (the two litters will be born separately).
What other animals represent?
One of the common animals is the lamb. According to the Bible, God had to test Abraham and let him kill his only son himself to show his sincerity. Abraham did, and when he raised his knife, God ordered an angel to stop him. At this time, Abraham happened to find a ram and took it as a sacrifice instead of his son.
Therefore, it is an old tradition to sacrifice sheep for festivals. Later, the lamb also symbolizes the son of God, because it is said that he was framed, took the sin for mankind, and was tortured on the gallows. Later, people had the custom of eating mutton on festivals.
