Legend has it, more than a thousand years ago, in the Gin dynasty of China, there was a person named Yue Guang. He has many friends, and he especially likes to invite friends to come over to have a drink and chat. Once at the banquet, a friend of Yue Guang saw a little snake wriggling in the glass while toasting. Although his friend was frightened, because of his pride, he had no choice but to force himself to drink up the wine. After he got home, he constantly felt like there’s a snake winding around in his stomach. The more he thought about it, the more uncomfortable he felt. He even ended up falling ill because of this!
