Husband and wife have different opinions, but their eyes are ruthless, they have food but no children, and their wealth is empty after half a life of marriage. What does this mean?

First, if there is a typo in your jargon, the second sentence is missing a word, and the original text should be:

Civil engineering couples have different opinions, ruthless opposition, food but no children, and half-life marriage has no money.

The first meaning is:

An ordinary couple always have different views, because their natural fates collide with each other, leading to the severance of friendship. There is no problem with food and clothing, but there are no descendants. After a half-life marriage, it is inevitable that you will have nothing!

This is a signature.

The second layer means:

(Civil couples have different opinions) One is earth and the other is wood. Land provides nutrients for trees, and trees protect soil from erosion. They care about each other, so they have different opinions. If you are separated, it will bring pain to your family and both sides ... (... you will have plenty of food and clothing all your life). Children listen to the scene; I won't bother you! You have laid a good foundation, but if you give up halfway in your marriage, you will go bankrupt.

This is a kind of recognition.

Haha, which one do you think you should believe?

Don't indulge in these things, be responsible for your own life, especially try to get along with your partner. Ask questions slowly and face them together. If you are a man, you have to take on more responsibilities.
