bug-out bag 紧急求生包

Bug-out bag is a bag that contains items needed in an emergency and that is ready for a person to take if they have to leave quickly in the event of a disaster.

“紧急求生包”即装有在紧急情况下需要物品的包，发生灾难需要迅速逃生时可以背上就走。

Example:

During his presentation, Mr. Charles suggested that a well-prepared bug-out bag was only part of the equation: just as important was knowing where to go.

查尔斯先生在演讲中说到，准备好一个“紧急求生包”只是成功的一半，同样重要的还有知道逃生到哪儿。
