How to understand the sentence "Women change their faces and men change their minds"?

Women are fickle, men are fickle. Undeniably, this sentence really reflects the sensibility of women and the characteristics that men should have in love to a certain extent. But I want to say that the meaning expressed in this sentence is objective and not comprehensive enough. It can be said that in today's daily life, women even treat feelings more than men.

In fact, many times, things in feelings can't be described as right or wrong. Whether men and women are in love, their IQ can't be measured by conventional models. However, women tend to be more emotional, and when they face emotions, they will naturally show it. For example, they will smile at anyone when they are unhappy, and they will not hide their inner joy when they are in a good mood suddenly. This is why most women like to express their psychological state simply and purely.

Men are generally more rational about feelings or other things. They can control their emotions well. Of course, although they can't be in a profound state of not liking things or being sad, they generally don't hang their mental state on their faces. For example, when a man loves you, no matter how spoiled you are, he is willing to love you and tolerate you. On the contrary, when he has no you in his heart, all your actions will have nothing to do with him.

In a word, the natural personality differences between men and women lead to their different ways of treating feelings. But I think this sentence is lacking and unfair. Is a woman's impetuousness really limited to changing her face? ! Or isn't the so-called man's change of heart caused by the fickleness of women? !
