Introduction to the moiré copper ban: Ban is a case that holds wine vessels. It originated in the early years of the Western Zhou Dynasty and disappeared during the Warring States Period. The reason why it is called "forbidden" is because the Zhou people concluded that the cause of the demise of the Xia and Shang dynasties was excessive drinking.
In Chinese history, Yu may be the first emperor to propose a ban on alcohol. According to legend, “The emperor’s daughter ordered Yi Di to make wine to make it beautiful. 'There will be people in future generations who will destroy their country with wine.'" The last kings of the Xia and Shang dynasties both lost their countries because of their addiction to wine. In view of this, Zhou issued the earliest prohibition on alcohol in China, the "Jiu Gao". Under this situation, although the princes and princes could drink alcohol during sacrifices, and even drank illegally, the cases holding the wine vessels were branded with China's first "Jiu Gao" The imprint of the "Prohibition" era - called "Alcohol Prohibition".
