Although proverbs cannot become classics in people's eyes like some literary works, we still mention them in life, and become some catchy words in people's eyes, these words are constantly transmitted, like a small invisible net, constantly draining those unpleasant words, and what is left behind are things that can stand up to scrutiny or can be affirmed by people in life, no matter when, Some popular words can always become classics in people's eyes in life. 
In all the sayings, we can distinguish right from wrong, and people always clearly make those things that they can't see clearly become clearer and clearer. Hence the words 'There are many rights and wrongs in front of the widow'. In feudal society, even in the later ** period when thinking was more free, people sneered at widows. At all times, people saw that the widow was not at all pity or help, but exerted all his strength to exclude him and snub her. 
Even in today's free and tolerant society, people still have a lot of criticism for widows, thinking that she is watery and does not abide by women's morals. felt that she should have been beaten to death with a stick and should not exist in this world. There has always been too much malice towards widows. In ancient times, a widow could not remarry in this life, and if she remarried, she would be disobedient to women's morals. People seem to have always been a derogatory term for widows, and they always look at them with colored glasses. 
Without a man, the widow still has to live. In a self-sufficient agrarian society, if they come out to farm, they should be greeted with endless abuse and accusations. I always feel that no matter what I do, I am wrong and looked down upon. The widow has endured so much alone. Since ancient times, some proverbs have paid attention to neatness and rigor. So people summed up the first half of the sentence 'There is less smoke on the roof of the widower'. A widower who has lost his wife must have had an upper meal and no lower meal. So there must have been very little smoke on the roofs of their houses. 
The summary of the proverb represents the state of life of most people, not necessarily for one-sided, nor necessarily partial, but we should still be able to see a broader life through one-sided.
