Answer:
The Stone Age was a broad prehistoric period during which stone was widely used to make tools with an edge, a point, or a percussion surface. The period lasted for roughly 3.4 million years,[1] and ended between 4,000 BCE and 2,000 BCE,[citation needed] with the advent of metalworking.
From at least 1766BCE to the twentieth century of the Common Era, China was ruled by dynasties. A dynasty is a family that passes control from one generation to the next. A dynasty does not have to last for a long
time. One Chinese
dynasty lasted
more than 800
years while
another lasted
only fifteen years.
