Why do you think that the area controlled by earlier dynasties grew larger under the control of each new dynasty in ancient china?

Because the new dynasties inherited the territories of the previous dynasty, a new "dynasty" is the establishment of a new government almost always interested in both social stability and military expansion.

What derives in the expansion of territories and control of new regions, more population, new people to pay taxes, more wealth for the nation.

is this from a story?

if so, can you tell which one?
