The extremely one-sided power of emperor-
The emperors were very suspicious on their officials and helpers might took over their place.
Policies were then carry out to concentrate the ruling power to the emperor only.
However,this came with heavy duties as well, once the one who inherited the role of absolute ruler was not hard-working enough, the government’s ruling would go down the slope.
The treatment towards the officials- the Ming emperor treated their officials very harshly as they wanted to show their supremacy.
The officials had to kneel before the emperor when they talk no matter who they are. They also had to call themselves “slaves” before the ruler, and whenever they did some mthing that upset the emperor they might get beaten, sometimes to death.
Given the situation,the officials tried their best not to interfere with ruling lest getting punished. This caused the ruling to be ineffective without the help of officials. Causing the ruling to went down hill eventually.
