一个人走在阳光下乘凉一个人走在黑暗下哭泣
[yī gè rén zŏu zài yáng guāng xià chéng liáng yī gè rén zŏu zài hēi àn xià kū qì]
A portrayal of someone who seems happy and composed on the surface (walking in the sunlight), but experiences inner turmoil and sorrow (crying in the dark). It conveys a dual nature of outward appearances versus hidden emotions.
