Among sing-song girls were actually several subclasses of high-end prostitutes divided by the quality of skill. Over time, these would evolve, beginning with one class, developing into four, and consolidating down to two. It was not until the founding of New China that the profession of prostitutes was abolished. •
Shuyu – The 書寓 (
shuyu) were the highest class. These were skilled in cultured entertainments. Additionally, these were picked for beauty, trained in sophisticated conversation, and known for their extravagant dress. The
shuyu would eventually become assimilated into the Changsan class of prostitutes. During the end of the Qing Dynasty and the beginning of the Republic of China, traditional
shuyu existed in name only. •
Changsan – The 長三 (
changsan, "long three") were the highest class of prostitutes in later stage. The term originally came from them charging three
yuan for company and three more to spend the night. They maintained the class and artistry akin to the
shuyu, while still being distinctly part of the sex trade. The relations between them and patrons were neither permanent nor monogamous. and pimps bought young girls and started teaching them basic talents from eleven or twelve years old. At thirteen or fourteen, they ended training and started singing on stage. At fifteen or sixteen, the laobaos (老鸨) and pimps gave them large numbers of obscene books to read, and they began to work as prostitutes. This is different from the traditional Gejis in ancient China, but during the Republic of China, many brothels would call these girls Gejis at will. The main business of prostitutes is prostitution, and they also earn extra income by chatting and drinking with clients. Accompanies guests to drink tea and chat, which is called "Da Cha Wei (打茶围)". They went out to participate in the service of drinking with customers, called "Chu Ju (出局)". Regardless of whether they are Chang San or Yao Er, they all have a unified title "guan ren (倌人)", which refers to prostitutes who are officially listed for business. If a client of a high-end prostitute wants to develop a long-term relationship with her, the client can also spend more money through the madam or laobao (老鸨) to maintain a "monogamous" relationship with the prostitute until the relationship ends. Underage prostitutes in Guangdong are called Pipa Zai (琵琶仔). They start prostitution after they become "adults" and are then called Lao Ju (老举). After their first client buys their virginity, they can only live for 10 days. After 10 days, the client must leave and the prostitute officially begins her prostitution career. ==Classes of other prostitutes==
