笑的撕心裂肺哭的没心没肺
[xiào de sī xīn liè fèi kū de méi xīn méi fèi]
This name describes a person with extreme emotional expressions; when laughing, it's as though their heart is torn apart, and when crying, they are so immersed in emotion as to seem heartless. It reflects an unrestrained, uninhibited personality who wears emotions on the sleeve.
