Fearless, the lady took the "poisoned wine" and gulped it down. As a result, she didn't die. It turned out that the pot was filled with vinegar, so the emperor used it to test her and made a joke. So the story of "jealousy" has been passed down through the ages as an interesting story. In modern life, some people will be jealous and jealous when they see others being praised or rewarded, and they are also dubbed "jealous".
Originally, this allusion was just a legend, and there were not many written records. However, Mr. Cao Xueqin, a famous writer in China, linked jealousy with jealousy in the 31st episode of A Dream of Red Mansions.
After Mr. Cao finished writing, he added the meaning of vinegar in Ci Hai: "I feel sad because of jealousy." "Jealousy" is extended to "jealousy", which is also from this. The legendary "Swallow Notes" in the Ming Dynasty also recorded that "the two are just jealous and suspicious, and they don't like each other".

The second is called "rotten vinegar theory". In the Qing dynasty, some people thought that jealousy originated from a prejudice. In some southern areas, people think it is not appropriate for a family to brew two jars of vinegar at the same time, otherwise one jar will be broken. Therefore, a family should not have two jars of vinegar at the same time. This is a metaphor: a family can only keep one wife, otherwise there will be jealousy between wives and concubines.
As early as the Southern and Northern Dynasties, the phenomenon of "bad vinegar" has been mentioned many times, which shows the difficulty of brewing. But it is far-fetched to say that two pots of home brew will destroy one pot, but it reflects the people's hope for monogamy.
