Legend of Ai Sima Yi in Three Kingdoms

Qin Ershi's death was due to his legalist thought of severe punishment and strict law, which led to tyranny. Qin Shihuang and Qin Ershi did not change their policies in time, which led to their demise.

But the other point is that Qin has always treated the people of the six Shandong countries as conquered peoples without mercy. You know, at the end of Qin dynasty, when the fog was the most diffuse, Guanzhong, the stronghold of Qin state, was still monolithic. Qin Shihuang toured the world and used the people's power mercilessly, all by this conqueror's gesture.

The people of the six countries could not stand this kind of slavery, and they rose up because of Qin's conquering attitude towards these people. The uprisings at the end of Qin dynasty were all under the banner of six countries, which just showed the people's yearning for the old country. You see, at the end of the Han Dynasty, when Zhuge Liang went to the Northern Expedition, he was not waiting for the big fellow to emigrate, but was heavily guarded in Guanzhong. At this time, it was only a few decades before the demise of the Han Dynasty, and Cao Wei really regarded his own people as his own. You can also look at the example of Wu Luanhua. Northern Han people always think about the northern expedition of 8 Jin Army. Even after nearly a hundred years, the troops of the Eastern Jin Dynasty and the Northern Expedition arrived near Chang 'an, and the people still said excitedly, I didn't expect to see them today, which was also caused by the conquest policy of the rulers of Hu on the people of Northern Han.
