What is the relationship between China's marriage "broken by a tiger snake" and "broken by a snake rabbit"?

Whether it is appropriate and harmonious for two people of different genera to get married and live together is called "crime" if it is not harmonious. According to the ancient fortune-telling theory, tigers and snakes are like knives, and the tears of dragons and rabbits are always flowing, and tigers and snakes kill each other. Marriage is rare, and the family must have money every year. Snakes and rabbits are compatible. These are just expressions in fortune telling.
