1. "A bird is lighter"
In the Northern Song Dynasty, there was a Chen Sheren in Bianjing who happened to get an old collection of Du Fu's poems. He was a treasure. However, due to the poor preservation of this book, many words in the poem have fallen off. Once, Mr. Chen read the poem "Send a Captain Cai" and found that the word "bird" was missing behind the sentence "one bird is light, one gun is urgent".
One day, when he was chatting with some poetry friends, he raised this question, hoping that everyone could make up the most appropriate word. Someone wrote the word "disease", which is considered to be the best performance of Cai Shu's brisk and fast dancing skills. Some people think it's not good because the word "sick" in the previous sentence and the word "urgent" in the next sentence are "as light as a bird's body" However, Chen Sheren thinks that the word "degree" is too blunt to show the characteristics of being as light as a bird. Some people even put forward the words "down", "up" and "down", but everyone was not satisfied.
Later, Sheren Chen found a relatively complete collection of Du Fu's poems elsewhere, and transferred the poem "To the Dutch" to Cai. The original sentence is "a bird is too light". The word "country" is a perfect way to describe the Dutchman Cai, who jumps high and fast, flying like a bird in front of his eyes.
