The entertainment quarters of Kaifeng, Hangzhou, and other cities featured amusements including snake charmers, sword swallowers, fortunetellers, acrobats, puppeteers, actors, storytellers, tea houses and restaurants, and brokers offering young women who could serve as hired maids, concubines, singing girls, or prostitutes. These entertainment quarters, covered bazaars known as "pleasure grounds", were places where strict social morals and formalities could be largely ignored. The pleasure grounds were located within the city, outside the ramparts near the gates, and in the suburbs; each was regulated by a state-appointed official. Games and entertainments were an all-day affair, while the taverns and singing girl houses were open until two o'clock in the morning. While being served by waiters and ladies who heated up wine for parties, drinking playboys in winehouses would often be approached by common folk called "idlers" ("xianhan") who offered to run errands, fetch and send money, and summon singing girls.
