What are the stories behind ancient poems, about one of the words?

The missing character in Prince Teng’s Pavilion is famous for its worth of gold.

"Where is the emperor's son in the pavilion now? Outside the threshold, the Yangtze River flows by itself." There is a big gap between "Yangtze River" and "ziliu". It is obviously that one word is missing. What is this word? Yan Boyu was puzzled, so he said to the other literati present: "Can any of you fill in this word?" After listening to Wang Bo's poems, the others already knew that their talents were not as good as Wang Bo's. Whenever I see that a word is missing from the poem, I am eager to try and fill in a good word. Someone said: "How about filling in the word 'water'? The water of the Yangtze River flows outside the threshold." Yan Boyu shook his head: "No, no, it will lose the artistic conception, wouldn't it become a monotonous scenery?" Someone else said : "What about adding 'Du'? Outside the threshold, the Yangtze River flows alone." Yan Boyu still shook his head: "No, this word 'Du' does not match the artistic conception of the previous article at all!" When the others heard this, they were silent. I can't think of a better answer.

Yan Boyu felt anxious when he saw that everyone could not figure it out, so he ordered his men: "Come here! Go after Wang Bo and ask him to fill in the word!"

Yan Boyu's men quickly caught up with Wang Bo and conveyed Yan Boyu's intention. Unexpectedly, after hearing this, Wang Bo waved his hand and said, "You can make up the words, every word is worth a fortune."

After the man listened, he returned to Yan Boyu and replied to Wang Bo's words. After hearing this, Yan Boyu said angrily: "A word is worth a thousand pieces of gold. How can a word be worth so much money." But not long after, he said to his subordinates: "Prepare a thousand taels of silver. This time I will go and beg him in person." Someone. Puzzled, he asked Yan Boyu: "Knowing that Wang Bo's words are not worth a thousand taels of silver, why did the governor agree?" Yan Boyu said: "The purpose of holding this banquet is to add glory to the reopening of Prince Teng's Pavilion, and secondly, It's to satisfy my love for talents. A mere thousand silver can help me fulfill two wishes at the same time. Besides, this matter has spread, and people with lofty ideals know that I am willing to pay for a word. Thousands of gold, are you afraid that no one will come to help you?" So Yan Boyu ordered people to prepare a thousand taels of silver and personally led a group of scholars at the banquet to rush to Wang Bo's residence, hoping that Wang Bo would fill in the word "younger". . When Wang Bo saw that Yan Boyu came to see him in person and brought a thousand taels of silver, he was a little moved and said politely: "Your Excellency, you are too polite to come in person after such a long journey." Yan Boyu cupped his hands and said, "I I came here to ask Mr. Wang to complete this poem." Wang Bo smiled slightly and said, "You have misunderstood. I never write empty words in my poems." Yan Boyu was stunned and took out the paper on which Wang Bo wrote the poem. "Yangtze River." There is indeed a gap between "" and "artesian flow". He asked puzzledly: "This place is obviously empty, and you still say it is never empty. Are you making fun of my stupidity?" Wang Bo shook his head and said: "Empty is empty. Where is the emperor's son in the pavilion now? After hearing this, Yan Boyu read it several times: "Empty Ziliu, Kong Ziliu, okay, okay, it turned out to be the word 'empty'!" ! ”
