Why don't men cry?

Self-esteem, men in China still have the feudal tradition of male chauvinism. This sentence itself covers these things. Of course, this is no one's fault, but for thousands of years, China's patriarchal social life is a relic; There is also the fact that women are naturally kinder than men (this is scientifically proven), so women are more likely to be moved to tears. Besides, isn't there another saying: men don't flick when they have tears, but they haven't reached the sad place yet ~ ~ ~
