Then Cao Chong's method of weighing elephants seemed really brilliant at that time. It is beyond a child's power to put forward such a method. Even now, this method is very scientific and almost impeccable. In addition to the current electronic scales and scales that can be called heavy things, are there other weighing methods for thousands of years?
The principle of Cao Chong's image reproduction is to use the method of equivalent substitution, and there is basically no error except a little trouble. There are other methods now or later, but at that time, Cao Chong's image method was the best, and other methods were not necessarily more scientific than Cao Cao's.
Therefore, because equivalent substitution is the method with the smallest error and closest to the real weight of elephants, before the invention of scales, the method of weighing elephants in ancient times was really limited, just as others said at that time that killing elephants was not a complete solution. After more than a thousand years, there was no suitable way to become a large animal.
Fortunately, elephants are not aggressive animals, so Cao Chong's method is very good. Unfortunately, as a child prodigy, Cao Chong died of the plague in 2008. This year, for Cao Cao, can be said to be an eventful autumn.
After pacifying Yecheng and Wuhuan in the north, Cao Cao, who was in high spirits, sent his troops south in an attempt to unify the whole country. Liu Biao, who occupied Jingzhou, died of illness, Liu Cong surrendered, and Cao Cao took Jingzhou as easy as blowing off dust, so he quickly wanted to take Jiangdong in one fell swoop.
As a result, because of the epidemic of plague, the army did not learn to fight in water, and Zhou Yu led the army to defeat Cao Cao's army. At that time, many people died of illness, which made Cao Cao's dream of unifying the world go away, but he turned his attention to Ma Chao and Zhang Lu in the northwest, stabilized his power and laid the foundation for his son to usurp the Han Dynasty.
When Cao Chong was alive, Cao Chong praised him many times for his cleverness and intended to let him inherit his career. Who knows that the defeat of Chibi not only lost the battle, but also led to the death of his beloved son, which provided convenience for Cao Pi and Cao Zhi to compete for a place later. Otherwise, the crooked history thought that xelloss could not be enthroned.
Smart people don't live long since ancient times. Many clever children either die young or grow up to be stupid, almost without exception. Maybe a person's intelligence is limited, so it's over.
