A " labor (labor) – saving device" is some tool or device or machine that saves you work.

“劳力(labor)-saving device” 是一些工具或装置或机器， 可以节省你的工作。

Perhaps the nearest modern equivalent in Anglo America is the Amish, a German American farming sect that largely renounces the products and labor saving devices of the industrial age.

在当代美洲的英语区，与民间文化最相似的群体也许算是Amish。Amish是美国的德裔农耕部落，他们基本上拒绝接受工业时代的大多数产品和节省劳力的设施。
