风儿并不疯沙子并不傻
[fēng ér bìng bù fēng shā zi bìng bù shă]
Literally meaning 'The Wind Isn't Crazy, The Sand Isn't Stupid', this phrase evokes a poetic and natural imagery. It implies that elements around us have their own rationale, suggesting everyone or everything has its own reasons for how it behaves or appears, beyond what we may first understand.
