What does it mean to be dark all your life?

There are many explanations for "there is a dark side of life" in the past, which need to be judged according to the previous context. For example, when it comes to marriage, "black" means asking you to have a mistress; For example, when talking about wealth, "taking the dark" means asking you to keep private money or hidden wealth and hidden property; For example, when it comes to children, "being hacked" requires you to have an illegitimate child. In ancient times, it mainly refers to having children by begging for a little wife and concubinage. Now ask the second wife and the third wife to have children. If you are a woman, understand it from a woman's point of view. Hehe, I just bought this passage from Baidu. But you have no context. You'd better post it so that I can refer to it. This passage is indeed more common in the theory that bones are hit.
