我不懂年少轻狂只知道胜者为王
[wŏ bù dŏng nián shăo qīng kuáng zhĭ zhī dào shèng zhĕ wéi wáng]
This translates to: 'I do not understand youthful recklessness; I only know that the victor is king.' It reflects the speaker's awareness of a ruthless, winner-takes-all mentality rather than understanding the carefree nature of youth.
