Introduce the patent of ancient wine-making invention.

It's none of their business that the poor are hungry and the rich go drinking. The low yield of ancient crops can only represent the average level of their agriculture, but not the upper and lower limits of a society. Therefore, in ancient times, there were wine pools and meat forests, and people fled in disaster years. It can be seen that wine was one of the upper limits of people in ancient times.

1. Wine is a symbol of ancient economy. The development of wine can show whether the economy of this dynasty is good or not. During the Three Kingdoms period, in order to save some food, alcohol was banned continuously. Although the Battle of the Three Kingdoms was terrible, the population of that era was directly reduced by two thirds, and it was inevitable that many people would starve to death. Looking back on the later dynasties, wine in the prosperous Tang Dynasty basically became synonymous with happiness, and poets such as Li Bai and Du Fu took turns to write poems for wine. In Song Dynasty, the economy was developed and the wine culture developed rapidly.

Second, wine can exist for a long time. Next, why did wine exist in every dynasty? Wine is one of the important ways for ancient people to enjoy life. In the Taiping period, wine was the entertainment for three or two friends to talk. Enjoying wine in non-peaceful times is a symbol of one's status. Social chaos and economic collapse may cause most people to drink alcohol, but the gap between the rich and the poor has always existed. Therefore, at this time, wine is only a special offering of a few people, and because of the scarcity principle, wine parties are becoming more and more precious, so people will make wine and collect wine. Therefore, no matter which era, wine has a reason to exist.

Third, the ratio of food to human beings is the decisive factor. Finally, the conditions mentioned in the title are too one-sided. The grain output in ancient times was really insignificant compared with the present, but the population in ancient times was very small. At the peak of the Han Dynasty, the population was 50 million. The population of the later dynasties was basically less than that of the Han Dynasty, and the population was generally maintained at 30 million to 40 million. It was not until the grain output soared during the Yongzheng period of the Qing Dynasty that the population officially broke through the 1 billion mark. So there was little demand for food in ancient times, as long as there was food.
