Du Kang Brewing Legend: It is said that Du Kang dreamed of an old man with a white beard one night and told Du Kang to give him a spring. Du Kang needs to find three different drops of human blood on the opposite mountain within nine days, and drop them into it to get the most beautiful drink in the world. Du Kang got up the next day and found a spring in front of her door, which was clear and transparent. So I went to the mountains to find three drops of blood. On the third day, Du Kang met a scholar and asked him to cut off his finger and drop a drop of blood. On the sixth day, I met a samurai. After Du Kang explained his purpose, the samurai decisively cut it down, and without saying anything, he shed a drop of blood. On the ninth day, Du Kang saw a man sleeping under a tree, covered in vomit and unbearable dirt, but the deadline had come, so Du Kang spent a penny or two on a drop of blood. After turning around, Du Kang dripped three drops of blood into the spring, and the spring immediately rolled, and the heat increased greatly, and the fragrance was fragrant and the product was like a fairy. Because it took nine days and three drops of blood, Du Kang named this drink "wine". Baidu Encyclopedia-Du Kang
