What kind of person was Emperor Wu of the Han Dynasty?

Emperor Wu of the Han Dynasty was a rough-hearted emperor. As an emperor, he is undoubtedly great. Apart from a hundred schools of thought contending, he only respected Confucianism and formulated strict laws to crack down on illegal acts of imperial power and national interests. Promulgate favor decrees, weaken the strength of governors, send secretariat, monitor all localities, counterattack Huns, recover Hexi Corridor, set up Fu Jia generals, fight against foreign dynasties headed by prime ministers, limit consorts' interference in politics, love literature, and appoint and appoint Dong Fangshuo. But he is also an autocratic emperor, self-centered, proud of the adulterer, believing in the art of fake law, cruel and unkind, ungrateful and cold-blooded. He has killed countless people in his life, and because of suspicion, he killed his wife, son and daughter. Two prime ministers, three daughters-in-law, a prince, a queen and two sons of Wei Qing were all slaughtered. I can only say that he is a great man, but he is not a good man.
