What's this sentence meaning?

do you have grass hoppers in China?





Imagine many grasshoppers, One leaps toward you, one leaps away from you one leaps over there, another leaps a different way, this is what "about" meants in this sentence. Many grass hoppers leaping in all different directions at once.

Have I helped you to understand.

In this context, "about" means "around" or maybe "all over the place." It's modifying "leap." "To leap about" is to leap repeatedly, in a generally random sort of way, all over the place.

My apologies, Dadpad! You must have posted that just as I was posting mine. Didn't mean to "override" you.
