In the early days of a dynasty, emperors were all good, and they all made great efforts to govern, and most of them had periods of rising national strength. However, in the middle and late period, although there were some ZTE masters, most emperors forgot the hardships of farming for generations from the beginning, and their problems came out, mainly as follows: 1, they didn't understand the social reality, lived in the palace all day, and lived like ivory towers; 2, do not work hard, lazy. Unwilling to go to court to handle government affairs, some even don't go to court for decades. 3, lascivious and lascivious. Love women, profligacy, resulting in national emptiness, heavy burden on the people. 4, the eyes and ears are not smart, and people are unknown. Pro-villain, minister of far Germany, ruler, power sidelined. 5. Arrogant and irritable. If you don't promise, you will be killed. These are all manifestations of "the disease of wealth", and when these situations appear, it is not far from the collapse of the dynasty.
