A joke says that women have two advantages.

Women have two advantages and one disadvantage. A person has no advantages, only one advantage. Men use their own advantages to make up for women's shortcomings, and women use their own two advantages to make up for men's advantages, so they are together, but in the end they are separated. Because everyone knows their own advantages and disadvantages, men feel that women have no advantages, and women feel that men have no advantages.
