俗话说,没有规矩不成方圆。现实生活中,“规则”无处不在,大到国际贸易规则,小到幼儿园小朋友做游戏的规则。《现代汉语词典》对于“常规”一词的解释有两种;一是沿袭下来经常实行的规矩;二是医学上称经常使用的处理方法。 As the saying goes, there is no rule that does not come in a square. In real life, “rules” are everywhere, as large as international trade rules, and rules as small as kindergarten kids do games. There are two explanations for the term “conventional” in the “Modern Chinese Dictionary”; one is the rules that are often followed down; the other is the medical treatment that is often used.
