侯门似海 is a Chinese idiom (chengyu) meaning “the gates of a noble or wealthy family are as deep and vast as the sea”. Implying their inaccessibility to common people and the strict social barriers. It also suggests that once someone enters such an elite circle, they become estranged from their former acquaintances due to differences in status and lifestyle, making it difficult to reconnect. Literally, “The gates of a marquis's residence are like the sea”.
During the Tang Dynasty, a scholar named Cui Jiao developed a deep affection for his aunt's maidservant. Their love was profound.
However, the maidservant was later sold to a powerful military governor, and they were separated, unable to meet.
One day, Cui Jiao unexpectedly encountered her on the road, but they could not exchange words.
Deeply moved and sorrowful, Cui Jiao composed a poem: 'Noblemen and princes follow in your wake, a beauty weeps, her tears moistening her silk scarf. Once inside the marquis's gate, as deep and vast as the sea, from that moment on, Xiao Lang (a poetic self-reference) is but a stranger.'
