Why is it said that as long as the older leftover man lowers his requirements for appearance, then a bunch of hard-working ugly women will be content to follow him for the rest of their lives?

This is indeed the case. In fact, older leftover men are all better off. How can a man with poor conditions become a leftover man? Just find someone and get married early. Just because my requirements are too high, I have never been able to find a woman who lowers her requirements and is not as good looking. Of course she is willing to spend her whole life with a man with such better conditions.
