月亮不会懂得太阳的耀眼太阳不会懂得月亮的盈缺
[yuè liàng bù huì dŏng dé tài yáng de yào yăn tài yáng bù huì dŏng dé yuè liàng de yíng quē]
'The moon doesn’t understand the brilliance of the sun; the sun doesn’t understand the waxing and waning of the moon.' This expresses mutual misunderstanding between two contrasting yet interconnected elements, suggesting everyone or thing has its unique attributes others cannot truly grasp or value, emphasizing differences in perspectives.
