Answer

Hi @Amirreza, you can find some examples of Boustrophedon writing here: https://en.wikipedia.org/wiki/Boustrophedon
Oxen is the plural of Ox - an animal which can be harnessed to a plough for farming.
Plowing is the American spelling of ploughing (pronounced the same "plowing"), which means to turn up the earth (for farming)
So oxen in ploughing refers to farming, where the oxen work in one direction, then turn and work back the other way in a parallel line, similar to how text is written in Boustrophedon.
