为你颠倒为爱退让
[wéi nĭ diān dăo wéi ài tuì ràng]
The phrase directly reads as 'I turn upside down for you and step back for love'. It depicts the depth of one's commitment, showing that they are willing to do whatever it takes, even sacrificing their own needs or going out of their way, just because of love or someone special to them.
