Women can't get married at 30? Is there such a saying?

I don't think there is a saying that a woman can't get married at the age of 30. In fact, no matter how old men and women are, as long as they reach the legal age for marriage and have the right marriage partner, they can register for marriage. Some people say they can't get married at the age of 30, or some people will look for someone to see them. They say they can't get married. If they can, they can postpone or advance, which is also possible. But this is unscientific.
