What are the allusions and origins of wine?

Legend has it that Du Kang could make wine, but he couldn't make it in those days. Later, he consulted a fortune teller, and the fortune teller told him that in a certain place, one drop of blood was taken from three people on a certain day, so that wine could be made successfully. So Du Kang went to the place designated by the fortune teller and waited for someone to draw blood. This is a remote path with small Woods on both sides.

A little later, a scholar came over, and Du Kang came forward to explain the reason, so the scholar dropped a drop of blood in Du Kang's wine. After the scholar left, another warrior stepped forward, and Du Kang stepped forward again to explain the reason. The samurai also dropped a drop of blood in the wine. After the samurai left, nobody came after waiting for a long time. Du Kang was worried, and it was almost over. If it passes, you can't make wine. what can I do? Du Kang was very happy and ran over. At first glance, he turned out to be a fool and felt very sad. He doesn't want to make wine with the blood of fools, but the moment is about to pass. Du Kang had to pull the fool to the side of the wine against his will and drop a drop of blood, so he got this wine.

Although it is caused by alcohol, people who drink late are affected by these three drops of blood.

When they started drinking, they were all gentle and polite, like scholars. After drinking for a while, they blushed, their necks were thick, their voices were loud and their voices were high, just like warriors. At the end of the drink, they were all drunk, their tongues were awkward, they were shaking when they walked, and their heads were in a mess, just like fools.
