The content of the whole poem is: a horse can take risks, farming is not as good as cattle;
A strong car can carry a load, but it is better to sail across the river.
Avoiding shortcomings is hard to find high resources;
Raw materials are expensive and applicable, and don't be too demanding.
A good horse can run thousands of miles, but it can't plow like an ox. A solid vehicle can carry loads, but it can't cross the river like a boat.
