Why were the Vikings able to do so much exploration during their time?

Vikings were nomads so they traveled and pillaged what they needed to survive they wouldn’t stay in one area for too long and would often move resulting in them traveling great distances

With Zheng death, the voyages ended. With pressure from the scholar officials, the ships were destroyed as well were records of the voyages. The Chinese felt that the expeditions cost more that the profits they made.
