青梅煮雨青梅煮酒
[qīng méi zhŭ yŭ qīng méi zhŭ jiŭ]
Based on the old idiom “Plum rains over Boiled Plums,” it means to reminisce the good old days with someone. This phrase also appears in classic Chinese literature, symbolizing the precious friendship during childhood and nostalgia over the passage of time.
