The evaluation of historical figures should be understood in the specific social environment.
Liu Bang and Liu Che in the Han Dynasty promoted the feudal unification.
Li Yuan and Li Shimin in the Tang Dynasty promoted the prosperity and development of the feudal society and created the "Zhenguan rule" in the history of China.
Zhu Yuanzhang and Judy in the Ming Dynasty promoted the further development of a unified multi-ethnic country.
Kangxi Qianlong in Qing Dynasty promoted the further prosperity and development of feudal society and reached the "prosperous time of Kangxi Qianlong".
Therefore, if we want to say who has made a great contribution, we can only consider it in the specific social environment, but we can't decide which one is bigger, because they have made outstanding contributions to the historical development of China and promoted the further development and consolidation of a unified multi-ethnic country.
