In the 13th year of Jian'an (208), Cao Cao felt the friendship of his good friend Cai Yong. When he learned that Cai Wenji was in the Southern Xiongnu and lived a difficult life, Cao Cao immediately sent Zhou Jin as an envoy, carrying a thousand taels of gold and a pair of white walls, and redeemed her. Then Cao Cao became the leader and asked her to marry Dong Si. After marrying Dong Si, she was often sad and distant and created the "Poem of Sorrow and Anger", which is also the first autobiographical five-character narrative poem in Chinese poetry history. In this year, the famous "Battle of Red Cliffs" started.

Cai Wenji married Dong Si. At first, the couple's life was not very harmonious. Cai Wenji was sad and often thought of her two sons. She often thought of her miserable life during the period of time in the Huns. Dong Si was in her prime, and she was born with a talented person, was proficient in calligraphy history, was familiar with music, and had a high opinion of herself. She was naturally a little dissatisfied with Cai Wenji. She always felt that her talent should be matched with an unmarried girl. She was very dissatisfied with Cai Wenji. In the second year after marriage, Dong Si was killed for a crime. She did not care about the rift and came to Cao Cao's prime minister's mansion barefoot to plead with her mercy. Cao Cao thought of his past friendship with Cai Yong, and thought of Cai Wenji's miserable life. If Dong Si was executed, Wen Ji would not survive, so she was spared from Dong Si.

According to folk legend, when Cai Wenji was pleading for Dong Si, Cao Cao felt very unbearable when he saw Cai Wenji's head and barefoot in the severe winter. He ordered people to take a turban, shoes and socks to change it for her, so that she could stay in her home before Dong Si returned. I don't know if it had been occupied by Cao Cao, a pervert. During a chat, Cao Cao expressed his envy of Cai Wenji's original collection of books. Cai Wenji told him that there were more than 4,000 books in his home, but after years of war, all of them have been lost. Cao Cao expressed deep disappointment. When he heard that Cai Wenji could recite 400 articles, he was overjoyed. So Cai Wenji wrote 400 articles based on his memory, and the article was completely misunderstood. It can be seen that Cai Wenji's talent and good memory are unimaginable.

From then on, Dong Si was grateful for his wife's kindness and re-evaluated Cai Wenji. Both of them also saw through the world and went up the Luo River to live in the foothills with beautiful scenery and lush trees. Several years later, Cao Cao passed by here hunting and visited him. Cai Wenji and Dong Si had a son and a daughter, and their daughter married Sima Yi's son Sima Shi as his wife.

A few days later, Lu Ning, Dian Wei and 500 "Night Eyes" arrived in Chenliu. After a lot of hardships, they found Cai Yong's mansion. Dian Wei stepped forward and knocked on the door of Cai's mansion. After a while, a servant walked out of the gate of Cai's mansion. Dian Wei handed Lu Ning's famous post (business card). The servant received Lu Ning's famous post and closed the door again, and turned around and went in.

After a while, the servant walked out with an old man of about 40 or 50 years old. Lu Ning knew that the old man should be Cai Yong. Lu Ning hurriedly bowed and bowed to him ninety degrees and said, "Lu Ning, a native of Jianning, met Cai Daru."

Cai Yong looked up at Lu Ning, looked at Lu Ning again with a strange look, and then said, "Are you really a big bear?"

Damn, why did Lu Ning meet someone every time he met someone, the first question of the other party was in the same language and the same tone. Could it be that he really had a bad reputation? Lu Ning shook his head and said respectfully: "I am Lu Ning, Zheng Ziyi."

When Cai Yong heard Lu Ning's confirmation again, he said, "Is it really a big bear?"

Lu Ning smiled and said, "Cai Daru, I am indeed Lu Ning, of course, the big bear you are talking about. This should not be fake. Besides, who else would be willing to pretend to be the famous big bear? Isn't that causing trouble for yourself?"

Cai Yong said to Lu Ning: "Mr. Zheng, I have lost my composure. I'm sorry, please forgive me."

Lu Ning smiled and said, "Cai Daru, don't call me an adult. You'd better call me Ziyi. This way I sounds more friendly. Who in the world knows that I am a person who is a fool, even Yanmen, Jinyang and other cities have been seized without orders. Now the emperor just asks me to help him watch first."

Cai Yong brought Lu Ning and the others into his mansion. Lu Ning asked more than a dozen "night-eyed" to carry the gift in, and the other "night-eyed" soldiers were all ambushed around Cai's mansion.

After the gift was brought in, Lu Ning said to Cai Yong: "Cai Daru, I have prepared a little gift for Miss Cai alone, please accept it together."

Lu Ning came to see Old Man Cai this time, but it cost a lot. He also asked Ma Jun to prepare a large mirror and a small and delicate mirror for the beautiful Cai Yan. Old Man Cai refused and accepted it after a little refusal. He also asked someone to send Beautiful Girl Cai’s gift to the inner room. Next, after Lu Ning and Cai Yong sat down, the servant brought tea and started to slowly taste the tea.

Cai Yong said: "Ziyi, how could you have time to come to my humble home?"

Lu Ning smiled and said, "Cai Daru, you are a famous Confucian scholar. You have a deep research on the lineage of qin. I will visit you this time to let Cai Daru be guided by me, an ignorant young man. Besides, I also heard that Cai Daru has a 'Jiaowei Qin', which has a wonderful tone and unparalleled sound when playing it."

Jiaoweiqin is a peerless treasure zither, one of the four famous zithers in my country. It is said that Cai Yong was wandering in a foreign land and lived in seclusion in the countryside. One day, Cai Yong sat in the room and sighed, feeling that God was really unfair to him. At this time, the landlord was burning fire in the stove next door. She stuffed firewood into the stove, and sparks jumped around, and the firewood was burned to a "crackling" sound. Cai Yong heard a crisp burst sound from the next door, and couldn't help but be shocked. He raised his head and raised his ears and listened carefully, shouted, jumped up and ran into the stove. When he arrived at the fire, Cai Yong didn't care about the fire, and reached out to pull the piece of paulownia wood that had just been stuffed into the stove as firewood.

When he took it out, Cai Yong's hands were burned. He didn't feel the pain. He was surprised to blow and touch the paulownia wood. At that time, the landlord thought he was in a state of mind and had a problem with his head. Fortunately, the rescue was timely and the paulownia wood was still complete, so Cai Yong bought it. Then he removed the scorched skin, adjusted the rhythm according to the palace and Shang, carved it carefully, meticulously, and worked hard to finally make this paulownia wood into a piano. When the piano was played, the tone was like the sound of nature, which was extremely moving. Later, the piano was passed down and became a rare treasure in the world. Because its tail was burned, it was also called "caused tail qin".

Cai Yong heard Lu Ning's words and said, "Ziyi, I have a piano, and I feel it's good, but I have never heard of the name of "Jiaoweiqin". However, I think the name is really good and considerate, so I will call it "Jiaoweiqin" in the future. But I wonder how Ziyi knows the origin of this piano?"
