(1) Not all wars are unjust wars. At that time, in the Central Plains, there were barbarians and backward Rongdi and Yi people in addition to the Huaxia nationality with relatively high social productivity and advanced civilization. They often attack the Huaxia nationality (especially the little Huaxia nationality), causing serious damage to social production. These small countries have played a progressive and just role in safeguarding their lives, property and advanced civilization in the war invaded by Emperor Rong.
(2) Under the above circumstances, the monarchs of some big countries, such as Qi Huangong, put forward the slogan of "respecting the king and rejecting the foreign countries" to unite with the Chinese people to resist the invasion of Yi Rongsuo Manli. Although he did this to improve his prestige and establish his hegemonic position, it objectively played a positive role in defending the advanced civilization and productivity of the Chinese nation from being destroyed, and it was a just progressive war. So even Confucius affirmed, saying, "I'm a little careless, but my hair is left-handed!" " "If there were no Qi Huangong and Guan Zhong, we would be conquered by the righteous emperor and become barbarians whose hair and clothes were buckled to the left! )
(3) Even a simple war for hegemony cannot be totally denied. Because it greatly reduced the number of vassal states and made the whole of China move towards reunification.
(4) The war objectively brought the Huaxia nationality into more frequent contact with the surrounding Yirongsuo Manli, thus promoting the ethnic integration. By the Qin and Han Dynasties, the Han nationality was gradually formed and national unity was consolidated.
It can be seen that the positive significance of the war in the Spring and Autumn Period is mainly from the historical height and long-term perspective.
