入座青楼
[rù zuò qīng lóu]
Historically in China, '青楼' refers to a place where artists, poets, and intellectuals would gather to share literary works and engage in intellectual discussions. Thus, '入座青楼' can be understood as stepping into an environment of cultural refinement and artistic inspiration. However, due to changes in social context over time, its meaning could also imply entering a pleasure house in modern interpretations.
