Although historical materials such as "Romance of the Three Kingdoms", "Book of the Later Han Dynasty", and "Zizhi Tongjian" have evaluated those historical figures, they are not obvious enough, and they are not intuitive enough to see the gap in their level, so I introduced a rating system in this book, according to the four attributes of leadership, strategy, command, and politics, and auxiliary attributes such as force and diplomacy to comprehensively evaluate those historical figures, and finally give a general evaluation.

Leadership mainly refers to the leadership ability of the monarch, which is generally only evaluated by princes, but some of the characters who stand alone will also have this evaluation;

Strategy is the main evaluation criterion of strategists, but it is not limited to strategists, mainly refers to the intellectual aspect, which is the solution and plan formulated through thinking about immediate and long-term problems;

Command mainly refers to military capabilities;

Politics mainly refers to the ability to do domestic affairs;

Armed force mainly refers to individual force;

Diplomacy mainly refers to the ability to negotiate.

In terms of personal evaluation, generally S stands for legend and epic; A stands for top; B stands for first-class, good; C stands for second-rate, general; D stands for poor, unqualified. Of course, there are also special circumstances, such as Cao Cao's force is B-, which does not mean that Cao Cao's force is relatively high, but that although Cao Cao's personal force is not much reflected, it cannot be ignored, that is, it is not easy to judge and relatively unimportant evaluation.

In terms of attribute evaluation, A+ is the highest value evaluation of ability, and S grade is an honor bonus, but the basis is still A+, and the lowest is D-, of which the cut-off point evaluation is A-level, and only the evaluation of A level and above (A-, A, A+, S-, S, S+) belongs to the top evaluation.

However, the comprehensive evaluation was S+ as the highest and C as the lowest, and it was divided into seven levels: S+, S, S-, A, B, C, and D. S+ represents the most core historical figure in the Three Kingdoms period, D is basically a passerby, and C- and D-level evaluations basically do not appear, because their influence is too small and there is no need to evaluate. Among them, S is the core level evaluation, A is the important level evaluation, B is more important, and C is basically not important.

The comprehensive evaluation of strength is only one aspect, and it is also related to many other conditions such as identity, environment, and influence, which is equivalent to the status of this person in the history of the Three Kingdoms.
