孟婆汤真酸奈何桥真长
[mèng pó tāng zhēn suān nài hé qiáo zhēn zhăng]
In traditional Chinese folklore beliefs and culture, Mengpo Soup is served by Mother Meng (a deity in Diyu) so newly deceased spirits can forget everything before starting new incarnations. But here, 'Meng Po’s soup tasting sour' symbolizes that the bitterness in the past memory is unforgettable. While ‘Nailuo Bridge seeming too long’ means one may feel the journey to reincarnation, like letting go of a love affair, will never finish. So, overall it expresses the pain of losing love.
