According to the data of the Kingdoms 11, this paper uses decision tree analysis to find out the distribution of the three generals ' characteristics. Variables include command, force, intelligence, politics, charisma, identity.
Variable Description:
Command: The defensive force of a military commander in the army. The higher the commander, the less the attack and the war of War are.
Force: The attacking force of a military commander in the army, the higher the Force is, the higher the damage to the local forces in the war of art or ordinary attack, and the higher the success rate, the less the difference between the two generals when they are singled out, and the greater the power of military commanders when they are singled out.
Intelligence: The effectiveness and success rate of military commanders when they are used, and when the generals have high intelligence, they can reduce their chances of being counted;
Politics: The ability of the generals to develop their internal affairs, the higher the internal affairs of the Interior, the production of weapons, the sale of fodder, construction time and other internal affairs departments have advantages. And politics has a vital role to play when it comes to searching for talent and dealing with hostile forces.
Charm: The higher the charisma, the higher the chance of success when the generals are able to use the opposition or other powerful generals. And when the generals recruit, the charm will also affect its effect.

Kingdoms each character has a certain identity, in addition to the monarch, there are waiters, advisers, generals, military attaches and civilian.

The general needs the Commander to increase the force in 150 to seal;
The adviser requires more than 90 of intelligence and adds more than 160 to politics.
