相遇城市迷失之前寻找似曾相识的脸
[xiāng yù chéng shì mí shī zhī qián xún zhăo sì céng xiāng shī de liăn]
Translated as 'Meeting you in the city, before getting lost, I try to find your familiar face', the nickname expresses searching for an acquaintance in an overwhelming urban setting, possibly referring to a chance meeting with a stranger who somehow seems very familiar.
