The ancient arguments about salt and iron are obvious, but since intense debate has been made in history, discussing the interests of the country is not new. During the Western Han Dynasty from 206 BC to 206 BC, discussions between these two occurred in the Zhao court of the Han Dynasty in 81 BC. On the part of the discussion, a senior government official was led by Dahon Minister. Government officials believe that salt and iron monopolies imposed by former emperor Wu are necessary for the country's success and safety. On the other hand, the group of Confucianists believe that these monopolies will lead to greed Such greed is not the right way, it will not only lead to the collapse of the country, but will also lead to a decline in human morality . The most important issue in any country is homeland security issue. People's safety is always a quick way to eliminate someone's emotions
"Theory of salt and iron" (Chinese: salt and iron theory; Pinyin: YánTiě Lùn) is an argument made in Chinese Han Dynasty court in 81 BC. Priest emperor Wu Emperor overturned its predecessor's laissez-faire policy, implemented various national interventions such as establishing monopoly right for Chinese salt-making enterprises and steel companies, price stabilization plan, capital tax and so on. These behaviors caused intense debate about the emperor's policy. During his death, during the reign of Wu Emperor in the Han Dynasty, Regent Hu Kwan demanded all the scholars of the empire to come to the capital city Chang'an to discuss government's economic policy.
