This sentence means that if a man has no wife, then the property has no owner and the man can't control his own money. In marriage, the wife's role is very important, and a good wife can keep the house in order. A virtuous wife is generally more careful, and every penny in the family will be spent on the cutting edge and will not spend money indiscriminately.
Because men are careless and neurotic, they are not as careful as girls and spend money lavishly, so they need to find a caring wife to help them take care of it.
The second half sentence is that if a woman has no husband, she will feel mentally and physically lonely and helpless. Because when a woman reaches the legal age of marriage, she will think about getting married, because her parents are getting old and can't accompany you for a lifetime.
As the old saying goes, a woman who has been single for a long time will feel lonely. When she is in trouble, she will be helpless without the help of a man, which will affect her physical and mental health for a long time. But in fact, as modern people, we get married later and later just to find the right person.
It is not unreasonable for the older generation to speak. But we don't think so now. We just want to find a person who likes himself, likes himself, and can spend his life safely. It is not urgent to meet these conditions.
