In addition, there were trade caravans and smugglers.
The Paratu officials sometimes allowed trade and at other times banned it. The winds of policy were always changing, but the demand was ever-present.
As the saying goes, "From the east come tobacco, liquor, oil, cloth, and sugar; from the west come cattle, sheep, mules, and horses."
When trade was allowed, they were trade caravans; when it was banned, they became smugglers, but all year round there were always people driving their teams back and forth between the Hurd tribes and Paratu.
Most of the time, the government of Paratu turned a blind eye—but that was regarding animals and miscellaneous goods like tobacco, liquor, sugar, and oil.
Any caravan daring to smuggle ironware, firearms, or gunpowder was unforgivable. Even if they had already crossed the midway point of the no-man's land, the Piaoqi of Paratu would hunt them down to the death.
