你要替我幸福下去
[nĭ yào tì wŏ xìng fú xià qù]
Ni Yao Ti Wo Xingfu Xiaqu: The phrase can be translated into English as 'You have to be happy on my behalf from now on.' There could be some sadness or helplessness inside, which means you need to live happily on my part because I couldn't make it, or because I hope you to be better after we separated.
