廣東話有一句: 好馬不吃回頭草! 用英文會點寫 ?

A good horse never eat the grass behing it,thats mean a good man
never look backward and he will not be shamed after he do
somethings.

As a good steed never turns back to graze on a trodden pasture !

（1）Good horse would never graze on the same pasture it just grazed before.
（2）A good horse will never turn round to graze on an old pasture.

A good horse will never turn round to graze on an old pasture.

The actual meaning is :

If you have ability & resigned from a job, you usually dont come back to the same post.

（1）Good horse would never graze on the same pasture it just grazed before.
（2）A good horse will never turn round to graze on an old pasture.
