南风伤了谁北风在念谁
[nán fēng shāng le shéi bĕi fēng zài niàn shéi]
This phrase contrasts the warm southern wind with the cold northern wind. It implies how different circumstances or times (warm season vs cold) can bring out varied feelings—such as nostalgia for some and sorrow for others, reflecting the changes brought by different periods and environments to people's emotions and relations.
