The last two lines of "Crane Soaring to the Sky" were replaced by a shallow pour and a low voice. These two poems directly caused his career to end.

Liu Yong can be said to be a famous figure in the world of Chinese poetry. When he was young, he was quite romantic by nature, because his family once served as an official, and he was quite prestigious in the local area. He was born in His father was still an official at that time, so he could be said to be well-dressed and well-fed, and had a lot of property to travel around. This was also the basis for his later descriptions of scenery to be so realistic.

Liu Yong prepared for the imperial examination when he was young. He was also very talented at that time and wrote many poems, which he passed on for a long time. Later, the imperial examination road made him suffer from setbacks. He took the imperial examination for the first time. , he originally thought that he would definitely become the number one scholar, but he failed because Zhenzong directly said at that time that he did not want the more gorgeous words, and then Liu Yong did not pass the exam, so he was indignant and started to complain. It was at this time that he wrote "Crane Soars to the Sky".

Later, he prepared for the second exam, but still failed. At this time, he began to hang out among the flowers. However, he still did not extinguish his desire to take the imperial examination, so he took the third exam. I also failed the exam 3 times. Under such a blow, he was unwilling to take the exam anymore and began to truly become a swinger.

In fact, he failed many exams, which is also related to his poem. According to unofficial records, after Song Zhenzong saw this poem, he disliked it very much, especially the last two sentences, "forbearance". The two sentences replaced the superficial name with a shallow drink and a low voice. These two sentences were a disparagement of the imperial examination, at least in the eyes of Song Zhenzong, so his path to the imperial examination was almost cut off.
