A widower generally refers to an elderly man who lives alone without a wife. In Mencius Liang Xia, there is a saying that "the old are widowed". A gun is actually a fish. The ancients used fish to describe a man who lost his wife because marlin walked alone all his life and never closed his eyes, which was very similar to the old man who lost his wife. So many literati often use marlin to refer to men who have lost their wives.

In Yuan Zhen's poem "Three Sorrow No.3", "However, I can look at it all night with my eyes open, and it will worry your brow all my life." He used the story of a widower to say that he wanted to be a widower. However, the meaning of widower in ancient times is still different from that of widower today, because a man may still have concubines after losing his wife, but he just doesn't remarry or straighten his side room, which is also a type of widower.

Ancient concubines could not become full members.

It is said that a daughter-in-law who has been married for many years can make a woman. However, in ancient times, after the death of a man's real wife, concubines could not become formal, because ancient people always followed the principle of "being suitable for each other" and "not marrying".

"My concubine is cheap", which is a moral constraint. I am not qualified to marry a lover. Therefore, after a man is widowed, most of them will choose a "second wife"-marry a good woman.
