Viewpoint 1: Not all day lilies are cold, but all cucumbers are cold! Cucumber itself is cold. If the cucumber is cold, it means that the time has been too long and the waiting time is too long, which means that this is not only a criticism of the latecomers, but also a mockery, and it will not hurt people's face. Viewpoint 2: This sentence was originally called "day lily is cold". In Qidong County, Hunan Province, which was rich in daylily in ancient times, after drinking and celebrating every festival, stewed daylily is an essential hangover remedy. The day lily is cold, which means that the host and guests sometimes forget the last hangover after drinking it, so some guests will complain why the day lily hasn't been served yet and say, hurry up, I'll wait for the day lily to get cold! The extended meaning is: waiting for a thing or a person for a long time is like waiting for the day lily on the vegetable table to get cold. Some people think that day lily is the last dish to sober up at a family dinner. If the last dish is cold, it will be too late. Viewpoint 3: "Cucumber" is probably a variant, which was originally "day lily"; And "day lily" is also a variant, originally "yellow flower". But this "yellow flower" is no longer a "day lily". In ancient poetry, "yellow flower" refers to chrysanthemum. Su Shi's famous sentence "Nanxiangzi?" The Ninth Han Hui Building was presented by Xu Junyou: "Everything is a dream in the end. Take a break, and Huang Die will be worried tomorrow. " The last sentence, "Butterfly will be sad tomorrow", was written on the Double Ninth Festival, that is, September 9th in the summer calendar. "Yellow flower" also refers to chrysanthemum. In ancient times, there was a custom of enjoying chrysanthemums on the Double Ninth Festival. "Tomorrow" refers to the second day of the Double Ninth Festival, which is September 10. "Huang Die will be sad tomorrow" means missing the best opportunity to enjoy chrysanthemums in Chongyang, and coming back after the festival, the flowers have withered, and bees and butterflies have lost interest, which is a metaphor for outdated things. Of course, this is the poet's exaggeration. Flowers may not wither overnight, but people's moods are different. If the simplest and most popular explanation is given for the phrase "Huang Die will be sad tomorrow", it is "late"-which means the same as "cucumber vegetables are cold". "Cucumber vegetables are cold" evolved from "Huang Die will be sad tomorrow". Just because Su's poems were so elegant, the people swallowed the dates and found them difficult to digest, so they passed them on. First, they turned "yellow flowers" into "day lilies" and later they became "cucumbers". The reason for this misunderstanding is that the word "butterfly" also has certain joint responsibility. Isn't it homophonic with food? So Dongpo's "yellow flower" finally became "cucumber dish" and was put into the "dish" It's "cold" if you come late. No matter which point of view is close to its original intention, the meaning of this sentence is recognized by everyone, that is, it is too late to wait for anyone and anything. What is the allusion? There is no way to prove it. However, I think the first view is that cucumber itself is cold. If the cucumber is cold, it means that it has been said for too long, and it seems a bit far-fetched to wait too long. Both the second view and the third view have some truth. If we have to trace the allusions, it seems that the point of view is reasonable, because many proverbs have been passed down from generation to generation for a long time, and of course great changes have taken place. There are many such situations, such as "the heart of a villain is the belly of a gentleman", which is quite different from the original words at that time.
