Translate the following phrase into Chinese. If society were a train, the etiquette would be the rails along which only the train could rumble forth; if society were a stagecoach, the etiquette would be the wheels and axis on which only the coach could roll forward. The lack of proprieties would make the most intimate friends turn to be the most decided enemies and the friendly or allied countries declare war against each other. We can find many examples in the history of mankind. Therefore I advise you to stand on ceremony before anyone else and to take pains not to do anything against etiquette lest you give offenses or make enemies.
