In celebration of Valentine's Day, special commemorative train tickets for a trip between Dàlín (大林) and Guīlái (歸來) were a big hit in Taiwan this morning.
In this case "Dalin" is treated as standing in for the English "darling."
So the Valentine's eve tickets are regarded as saying "Darling, guīlái", i.e., "Darling, come back."
Happy Valentine's Day, everyone! (I take it as license to indulge in extra chocolate.)
