你后来牵谁的手为谁挡着风
[nĭ hòu lái qiān shéi de shŏu wéi shéi dăng zhe fēng]
'你后来牵谁的手为谁挡着风'(Nǐ hòulái qiān shuí de shǒu wèi shuí dǎng zhe fēng) means 'Whose hand you held later and whom you protected from wind afterwards.' This portrays a reflective tone about changes in love, asking whose hand the addressed used to hold now holds another and how their care (blocking wind) has also turned towards someone new after a transition or evolution within their romantic life.
