Goods
were traded for products. That’s their way of exchanging goods without the use
of gold or silver. Instead of paying money or gold or silver to get the goods
that they need, they traded it with other products. It is somewhat the same
with barter system in which people exchange goods and products to get what they
want.
For example:
=> A sack rice is traded for a porcelain
=> The vegetables were traded in exchange of meat.
