我有病你是药我是树你是根
[wŏ yŏu bìng nĭ shì yào wŏ shì shù nĭ shì gēn]
'I am ill and you are my medicine, I am a tree and you are its root.' This nickname portrays a dependency between two people, similar to that between a patient and healer, or tree (symbolically oneself) sustained by the roots (another person), indicating the speaker's need for this other individual as an essential support system.
