如何使用中国公厕？(外国人总结小窍门)

英国每日电讯:中国科学家研制新式武器,清除公共厕所中的难闻臭味儿.中国科学院的研究人员表示,最多能有75%的臭味被清除掉,其余的则可以通过自然,令人感到舒适的香气盖掉.这种不可思议的魔力主要来自于乳酸菌属的细菌,它们以人类的废弃物为食,释放出乳酸,能够抑制大多数产生臭味的细菌生长繁殖. 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.
