Note: 开始“礼仪”用了manners，交作业的时候误看到愚公的etiquette了，就改成etiquette。轴：查了字典知道是axle的。
What etiquette is to a society is like clothes to an individual. An individual without clothes would be ridiculed for being naked and cause deterioration of morals. Without etiquette, a society would be in a mess and the necessary interaction between members of the society would be disrupted by meaningless conflicts and turmoil. If the society were a train, then etiquette would be like the rail along which can the train march. If the society were a carriage, etiquette would be like the wheels and axles, only with which can the carriage go forward. Without etiquette, the closest friends would become enemies and allies or unions of countries would fight with each other. We can find many examples like this in the human history. Therefore, I suggest you to obey the etiquette when dealing with anyone, and try not to do things against it, in avoidance of offending others or making enemies.
