如果你是许仙我定是白娘子
[rú guŏ nĭ shì xŭ xiān wŏ dìng shì bái niáng zi]
'If you are Xu Xian, then I am surely Bai Niangzi.' This name originates from Chinese classic legend about Xu Xian and the White Snake (Bai Niangzi). Here the person compares themselves to Bai Niangzi and desires to share an immortal romantic story like that.
