Think about it, the ancient emperors were handed down from one family to another, and the feudal dynasty practiced a system of one family to the world. Under normal circumstances, the imperial power will not be handed over unless someone revolts. Why should Shandong people rebel while living a good life? Is it because you are full?
Zhu Yuanzhang, the founding emperor of the Ming Dynasty, was born at the grassroots level and was a child of a poor family. He himself said: In that year, whenever there was a mouth to eat and barely lived, there was no Zhu Yuanzhang, the founder of Ming Dynasty, but only a farmer Zhu Yuanzhang.
The peasant class in Shandong is located in the Yellow River valley, which has natural advantages in farming and fertile land. There is really no need to risk your life to rebel.
Let me talk about the literati class again. They have accepted Confucius since ancient times. Jun Jun chenchen? The baptism of thought holds that the monarch is destined to rule the world, and his mission is to help the monarch rule the world and make people's lives happier. Worship each other is their pursuit.
As for rebelling against regicide, or replacing it by themselves, it is a heinous act in their eyes, and they will never have such a mind. As Confucianism, they are full of thoughts? Loyalty and patriotism? They are also the staunchest fans around the Emperor.
The last point is geographical factors. Shandong is located in the plain, and there are no natural barriers and mountains around it. If you really want to rebel and become an emperor, you will soon be wiped out by the army. Shandong area is mostly literati, and its fighting capacity is not strong. They have no force, no geographical advantage and no reason to rebel. Why kill yourself?
Therefore, during the feudal dynasty of thousands of years, there was no emperor in Shandong, but many literati and princes were trained.
