你是风你是沙
[nĭ shì fēng nĭ shì shā]
Translated literally into 'You're the wind; you're the sand'. Wind is transient, hard-to-grasp and intangible. Like the drifting, fine granules of sand stirred up by winds and floating about, the phrase could convey an appreciation for the free and unpredictable nature of oneself or others.
