Due to the gigantic difference in territory size between the other states and Chu, the difference in population between them is equally large. In other words, the number of people they are competing against is also different. However, Chu does not field a greater number of generals compared to any other state. This means that those that manage to climb to the top of the mountain in Chu have done so only after passing trials that are incomparable to other states. Only the absolute cream of the crop are capable of reaching the rank of general in Chu. It is commonly accepted in Chu that their generals are on par with the great generals of all the other states.
