Last year, there was a hot event in which the president of Peking University publicly apologized to the people of the whole country. The reason is that he mispronounced a word at the graduation ceremony of Peking University. Which word? He interpreted Yu Hong's ambition as Hong Hao's ambition. What happened to this swan?

This word is not particularly rare. Everyone learned it in middle school. From Sima Qian's Historical Records, "Chen She Aristocratic Family". Chen She is Chen Sheng, his surname is Chen Mingsheng, and he was the leader of the peasant uprising in the late Qin Dynasty. When he was young, he said a grandiose sentence: birds know the ambition of a swan? So, what kind of bird is a swan?

On this question, Baidu asked, some said it was a goose, and some said it was a swan. In fact, the swan fights with the sparrow in front, which refers to two kinds of birds. Generally speaking, swans refer to wild geese, and it is often said that swans fly south; Siniperca chuatsi (hu2) refers to swans. They are close relatives, belonging to Rhamnaceae, and they are all migratory birds.

Today, I mainly talk about this mandarin fish, which is also a swan. Swan is the tallest bird in the world. It can fly to an altitude of 9000 meters. This height has exceeded the highest mountain on earth, in other words, nothing on earth can stop them. Every year, swans fly over Mount Everest, the roof of the world, and spend the winter in Nepal in the south. This is really no ordinary bird.

Then why did the ancients give the swan a name? Compared with swans, it is much easier to understand!

Let's take the word mandarin fish apart and say:

Mandarin fish = (cow+mouth)+bird

Besides appearance, birds are also a species. It is said that the ancients sacrificed cattle to the gods and prayed for happiness.

In the eyes of the ancients, swan is a kind of bird that can bring people's blessings to the sky, so it is called "mandarin fish".
