As for why alcohol should be banned, it goes without saying. Disadvantages, coupled with so many examples in history, must be known to everyone.
The first is the control of wine in the Western Zhou Dynasty. During the reign of the last ruler of Xia and Shang Dynasties, wine played an important role in accelerating the demise of the dynasty. Therefore, the Western Zhou Dynasty deeply absorbed the valuable experience left by the previous generation and hated alcohol, becoming the first dynasty to control alcohol in history. Later, many dynasties also revised and compiled the wine system of the Western Zhou Dynasty.
Shang Yang of Qin paid great attention to the savings of national strength, and it happened that he regarded wine as a kind of high-cost consumer goods, so the prohibition system passed down from generation to generation was further deepened in Qin.
The same is true of the Western Han Dynasty, which inherited the prohibition of alcohol from the Qin Dynasty. Moreover, when the Han Dynasty was just established, the society was still in turmoil. At that time, in order to prevent the reactionary forces from making trouble at that time, the rulers added another item to the toast system-three or more people drinking together should be fined four taels of gold.
In the Tang dynasty, on the basis of banning alcohol, the rulers added some regulations on selling and making alcohol, and private brewing was not allowed.
In Song Dynasty, wine tax had become an important source of national capital at that time. Like the Tang Dynasty, the Song Dynasty also regulated private brewing. If the official finds that the brewing exceeds 5 kilograms, he will be sentenced to death.
In addition, it is worth mentioning that among these dynasties, although the Qing Dynasty was in a relatively backward time position, it was the dynasty with the heaviest wine tax.
For drinks, not only these, but also many dynasties held an attitude of explicit prohibition, which shows the great harm of ancient drinks in China.
