The six blind men earned their living by begging on the road

有没有变化格式?
如果没有的话,则有N种变化方式,比如：
The six blind men earned their living by begging on the roadside.
= The six blind men earned a living by begging on the roadside.
= The six blind men made a/their living by begging on the roadside.
= The six blind men lived by begging on the roadside.
一楼的变化没有注意时态,应该是：
= The six blind men begged on the roadside to earn/make a/their living.
注：/ 表示可以任意选用其一.
