First, during the Spring and Autumn Period, although the Zhou family declined, the moral concept of advocating propriety and righteousness, loyalty to the monarch and loving the people still prevailed in society. Although the vassal States are fighting in secret, they are unwilling to trample on morality and make other countries look down upon it. Therefore, in diplomacy, envoys often seize this aspect and convince each other by stating "righteousness". In Peace in the Song and Chu Dynasties, Xie Yang said: "A monarch can control his life as righteousness, a minister can accept his life as a letter, and the letter carries righteousness for profit, to protect the country and defend the country for the people, and to be loyal and trustworthy." Righteously, the king of Chu was deeply moved.

Second, under the complicated and changeable situation in the Spring and Autumn Period, wars between vassal states often take the form of contractual cooperation, and when interests are obtained, there will be distribution problems. Diplomatic envoys often seize this point and provoke allies, thus disintegrating their United front and reversing the unfavorable situation. In Candlelight Martial Arts Retire Qin Shi, Candlelight Martial Arts "give priority to neighbors", which split the cooperation between Qi and Jin, and saved Zheng from the danger of national subjugation.
