中国公厕的臭味

　　The Telegraph: After three years of research, Chinese scientists say they can turn even the most putrid public lavatory into a sweet-smelling sanctuary.

　　Many people believe that entering a public lavatory in China can be a horrifying experience.

　　In smaller cities, or the countryside, the sight of an open trench, coupled with a suffocating stench of sulphur and ammonia, is often enough to send even the bravest tourist whimpering back to their hotel.

　　Today, however, Chinese scientists have claimed victory in their battle to improve public rest rooms, unveiling a bacterial spray that can, they say, almost eliminate the smell of putrefaction.
