山中无老虎 猴子称霸王

When the cat's away, the mice will play.

山中无老虎，猴子称霸王。

When the cat's away, the mice will play.直译过来就是：“猫儿不在家，耗子就会出来活动”，这个短语的正确意思是：“山中无老虎，猴子称霸王”。因此，当美国人说"When the cat's away, the mice will play."时，他/她要表达的意思就是:"The subordinates will do as they like when the superior is away."、"The weak will become active without the strong."。
