"Imagine you are a Berlin resident on the day of November 9, 1989. You learn about the news that the Berlin Wall is being torn down. Write a journal entry capturing your emotions, thoughts, and experiences as you witness. Reflect on the significance of the wall's collapse, the hopes it inspires, and the challenges that lie ahead for a united Berlin and Germany."

Why did Cao Cao do this? I think the most likely reason is that he is afraid of being robbed, because he has done this kind of immoral thing. Cao Cao made his fortune by suppressing the Yellow Turbong Army. When Zhang Jiao died of illness in Guangzong and the Yellow Turbong Uprising failed, the generals of the Yellow Turbong set up many fake tombs near Guangzong in order to protect the leader's bones and lure the official army with money. The official army searched the tomb of Zhang Jiao with the stone tablet of the Great Scholar and good teacher, but they could not find Zhang Jiao's bones. After all the torture of the captives, the captive finally got to know the real Zhangjiao tomb, personally led the army to Zhangjiao's hometown, Ju Lu, found Zhangjiao tomb under the old Zhanghe river trough, cut off the head and threw the body into the river, and then took Zhang Jiao's head to Beijing to receive the reward. Later, during the battle of The Three Kingdoms, Cao Cao in order to deal with the question of his own food and pay also established a lieutenant who touched gold, and the official post of a doctor such as the doctor of hair Qiu was specialized in robbing tombs, which is equivalent to the current archaeological experts of cultural relics. It should be known that after the rule of Wenjing in the Western Han Dynasty, the productive forces of the peaceful society in the world were fully brought into play, and the prosperous economy made heavy burials popular at that time. Cao Cao's army of tomb raiders dug up tombs everywhere to collect gold and silver treasures to pay the army. Historical records show that Cao Cao's tomb raiding income supported Cao Wei's army for three years. Perhaps it is more than a tomb robber, witnessed too many grave goods stolen after the tomb robbery, the bones were thrown into the wilderness, Cao Cao realized a thick burial will recruit the truth of the tomb robber, Cao Cao will request a thin burial, but also afraid of making a self-theft to build a suspected tomb to lure the world.
