What, in addition to geographic boundaries, might have kept the people of the huang river civilization from traveling to far-distant regions? they feared that their bronze weapons would be no match for the iron weapons of ancient egypt. they could get everything locally that they needed to survive and grow. they had learned about the other river valley civilizations but feared contact would bring invasion. they had not yet developed a system of money based on coins.

The Huang or Yellow River civilization is one of the oldest sites of civilization in world history, going back to 4000 BCE. China is a highly diverse geographic region, with mountains surrounding the Huang River region. This made a large population of China reside near the river on the eastern side of China, because they could get everything locally that they needed in order to survive and grow. Even today, the Huang River remains a densely populated region to the abundance of rich soil and resources available.
