Moreover, from the root, the decline in the middle and late Ming Dynasty was directly related to Zhu Yuanzhang. During the Chongzhen dynasty, the central government could not collect military expenses to fight. This is because the descendants of Zhu surname were fixed when Zhu Yuanzhang was in office, and all of them were raised by the court from the central finance. However, at the end of the Ming Dynasty, with the prosperity of Zhujiajian's children and grandchildren, the number of people soared, which became an extremely exaggerated amount.
Even if future generations know of such ills, who can easily disobey Mao's teachings, and if they dare to make changes, the throne is legally rejected. Therefore, when Zhu Yuanzhang led the army through, the first thing to be solved was his own rules, and it would be easier to solve the money and food of the army. However, the combat effectiveness of the army in the early Ming Dynasty was also very different from that in the late Ming Dynasty. It can be said that if Ming Taizu's army turned over at the end of the Ming Dynasty, except for a few elite troops, others could flee at any time.
There is nothing wrong with the strategy of "staying at home first" Even if Zhu Yuanzhang goes back, he must first stabilize the latter, and then save the national strength for the foreign enemy after destroying the thief. However, the late Jin Dynasty is not an easy opponent, and they will not let Zhu Yuanzhang simply wipe out the so-called thieves in the south. Therefore, if Zhu Yuanzhang returns to this period, the first thing he has to face is his own chaotic structure. It would be nice if he didn't get angry when he saw his structural deformation.
