Instead of using the more gender general term "mei ren" (媒人), texts more frequently referred to marriage brokers as "mei po" (媒婆). Since "Po" (婆) translates to "grannies" in English, it suggests that elderly female characters dominated the "marriage market". Indeed, in the novel "The Golden Lotus" (Jing Ping Mei), the four matchmakers Wang, Xue, Wen, Feng were all elderly female characters. In ancient China, people believed that marriages belong to the "Yin" side (the opposite is "Yang"), which corresponds to females. In order to maintain the balance between Yin and Yang, women should not interfere with the Yang side and men should not interfere with the Yin side. Since breaking the balance may lead to disorder and misfortune, men were rarely seen in marriage arrangements. Furthermore, unmarried girls were not in the occupation because they themselves knew little about marriage and were not credible in arranging marriages. As a result, almost all marriage brokers in the literary work were presented as elderly females.
