After a day of exhaustion, the urn salesman, well-off (Li Kangsheng), sneaked into a room in an apartment. Unexpectedly, he would sneak into a stall vendor (Chen Zhaorong) who would be the object of his desire. The temporary owner of the house is a salesgirl (Yang Guimei). Although she and the well-off have different sexual orientation, they are also people who have no love (emotion) to warm their hearts. At the beginning, well-off and stall vendors always beware (salesgirls and each other). After they get to know their respective lives, they beware of psychological elimination, but they have not become friends ever since (cowardly well-off people do not have the courage to show their love). The salesgirl and the stall hawker have had sex several times, clearly understanding that each other is to satisfy the long-term physical hunger and thirst, love (feelings) is not long-lived, physical pleasure can be temporarily satisfied, but spiritual comfort can not be obtained (even if there is, it is as short as fireworks).
