What is the poem "Driving in an array for the road, flying guns across the river and breaking heavy buildings"?

The two countries fought for hegemony and got something for nothing.

The horse will cross the gap in two steps and leave Mimia beside Xi Liuying.

Get off the bus for the main road, fly guns across the river and break the heavy city.

The situation has changed a lot, and when we see one soldier and one pawn, we live in peace.
