from wu qi, the fourth century b.c. chinese version of jared taylor (~_^) [pg. 12 – links added by me]:

Qin‘s nature is strong. Its terrain is difficult. Its government is severe. Its rewards and punishments are reliable. Its people do not yield; they are all belligerent. Therefore they scatter and fight as individuals. As the way to attack them, one must first entice them with profit and lead them away. Their officers are greedy for gain and will separate from their generals. Take advantage of their separation to attack them when scattered, set traps and seize the key moment, then their generals can be captured.

Chu‘s nature is weak. Its terrain is broad. Its government is disorderly. Its people are weary. Therefore when placed in formations they cannot maintain them long. As the way to attack them, strike and cause disorder in their camp. First ruin their morale by nimbly advancing and then rapidly withdrawing. Cause them fatigue and toil. Do not join in actual combat, and their army can be destroyed.”

apparently, wu characterized all of the nine cultural regions of china at the time like this, but i haven’t found them yet (to be honest, i haven’t looked that hard).
