黑夜不知太阳的耀眼
[hēi yè bù zhī tài yáng de yào yăn]
The Night Doesn't Know the Brilliance of the Sun expresses the idea that something or someone is unable to understand or appreciate another's significance or greatness. It might convey the feeling of being underappreciated or misunderstood, especially in the absence of mutual understanding or context.
