Second son: It's about money, which means that you can't manage your money without restraint. Although there is money in life, you earn more and spend more.
Third son: it's about your feelings. You may have an affair or change your mind. I advise you to be careful and not to go the wrong way.
Fourth, it can be said that it is a summary of life, saying that everything follows fate and everything cannot be forced!
Finally, I want to tell you that all evil should be done and all good should be pursued.
