The Elegy of Imperial Rejuvenation: Seven Lectures of Emperor Chongzhen: Zhu Youjian, the emperor of Chongzhen, who was seriously lacking in maternal love since childhood, could only hide his strength and hide his strength to protect himself in the sinister court politics. However, fate pushed him to the throne of the emperor almost overnight. Using his political wisdom, he quietly wiped out the official party group headed by Wei Zhongxian, returned politics to himself, and carried out drastic reforms in order to "rejuvenate". It should be said that the personal character of Yu Jian was quite good among the emperors of the Ming Dynasty. However, the mess left by the Wanli Dynasty is really riddled with holes and will soon perish. Just like Taizu Yuanzhang's mentality and practice of "too much punishment" and "too quick to seek treatment", Yu Jian also learned from Taizu the profound suspicion of his lieutenants, coupled with his lack of political experience and improper measures, and finally staged the life tragedy of "the king who did not perish" in the predicament of "national subjugation". It is a typical non-historical subjective statement to attribute the poverty, backwardness, chaos and humiliation of modern China to the death of Ming Dynasty and the prosperity of Qing Dynasty. Behind this statement, I vaguely want to tell people that China's traditional society can also produce modernization factors and gradually embark on the road of modernization. And what are the historical facts? East and West met in Chongzhen Dynasty, but East was defeated. Why on earth is this? Mr. Zhang Dexin and Mr. Tan Tianxing, famous experts in Ming history, will elaborate on this history for you.
