Li Mo was the chief piper in the Kaiyuan period of Tang Dynasty. Li Mo used to play the flute in Guazhou. At that time, there were many ships on the river and people were noisy. When Li Mo blew the first flute, the noise stopped at once. After playing for a few days, there seems to be a breeze on the quiet river. In a short time, the boat people and Jia Ke in the whole river sent out sad voices, and the feelings of sadness, sigh, sadness and resentment were beyond words. At that time, people said that Li Mo played the flute, which was the best in the world.

Once, he boarded a boat with several guests, swam across the river and played the flute to enjoy the moon at night when the moon was high. The flute is wide, clear and elegant. Suddenly someone on the shore called and asked to get on the boat and swim together. Li Mo and others stopped at the shore of the ship. When the man got on the boat, he borrowed a flute from Li Mo and let him play a song. The flute played by this man is exquisite enough to break rocks, which Li Moping has never heard of. At the beginning, the flute sounded extraordinary when it was blown to the loose sequence and the middle sequence. When I entered the third broken section, I saw the piper's breath hovering and turning, and his fingering was broken like rain hitting the window. Listen to the flute again, like a thousand troops tearing and roaring, like rain hitting the beach. On another occasion, Li Mo asked for leave to go to Yuezhou. When he arrived in Yuezhou, local dignitaries held a public banquet or a private banquet for him so that he could hear the flute he played with his own eyes. At that time, just a dozen freshmen from Yuezhou were admitted to Jinshi. These families have some industries, so they collected 2,000 pence to drink and have fun on the Jinghu cruise ship, and invited Li Mo to play the flute on the boat to satisfy their ears. Because there are more people and less money, it is agreed that each person can bring one guest.

One of the people who attended the party didn't remember until the evening and didn't have time to invite others. Please invite a lonely old man in the nearby community. The old man lived in Alatano for a long time and knew nothing about the personnel accidents outside. He lives alone in several huts, and people in the village call him Duguzhang. The next day, Jinshi and his father-in-law went to the place where Jinghu met.

After the banquet, I saw the lake clear, blue waves rippling, lush grass and extraordinary scenery. Li Mo waved his flute and stood by the boat. With the sound of oars, the boat gradually moved towards the middle of the lake. At this time, the light clouds cage the lake, the breeze blows the waves, and the waves are urgent. Li Mo played the flute with his hand. When the flute sounded, the clouds opened and the water was bright, as if there were ghosts and gods! The guests on board were surprised and said, "Even the joy of God's offering sacrifices to heaven is not so great!" " "DuGuZhang said nothing. Everyone at the meeting was unhappy. Li Mo also thought that the old man looked down on himself, became angry and became silent. After a long time, I meditated and played another song. The music was even more wonderful and unusual, and all the guests present were amazed and appreciated, but Du Guzhang still didn't say a word. The Jinshi who came to invite him was also deeply ashamed and explained to the guests at the same table: "Lao Zhang lives alone in the mountain village all the year round, does not associate with people, and rarely goes to town." He knows nothing about music, please don't mind. " The guests of four seats laughed at Lao Zhang at the same time, and Lao Zhang kept silent all the time, only smiled slightly.

Li Mo asked, "The old man didn't say a word. Do you really know nothing about music? Still a master? " Zhang Dugu said slowly, "How do you know I don't understand music?" When the four guests saw Li Mo's face changed, they all stood up to apologize to Li Mo and comfort him. Just then, Zhang Gu said quietly, "Please try to fight Liangzhou." Li Mochou played a song "Liangzhou" slowly on his flute. At the end of the song, Zhang Gu said, "Gong Li plays the flute really well. However, your flute is mixed with Yidi music. Do you have any friends in Qiuci? " Li Mo was taken aback. He stood up to pay homage to Zhang Gu and said, "Lao Zhang is a strange man outside the Party. It's a pity that Li Mo is blind. My teacher is really from Qiuci. " Zhang Dugu added, "You blew Liangzhou's tune to the thirteenth stack, and it went wrong. Do you know it yourself? " Li sincerely replied: "Li Moyu is stupid, I really don't know." Zhang Dugu reached for the flute and showed it to Li Mo. Li Mo hurriedly changed a flute, wiped it with his sleeve and handed it to Zhang Gu. Grandfather Dugu took it and said, "These flutes of yours don't work well. The owners who use them are all proficient in flute. " So he changed another flute and said, "You won't be reluctant to part with this flute when it blows into the hole." Li Mo said, "I dare not." So Grandfather Dugu played the flute. At the beginning of the flute, the sky stopped and four seats were shocked. Li Mo stood there respectfully and uneasily, not daring to move. In the thirteenth stack, Zhang Dugu stopped and explained to Li Mo the fallacy he had just blown. Li Mo completely obeyed and thanked him repeatedly. It's broken. The flute is broken at once. It can't be played any more. Li Mo thanked him again, and all the guests were completely moved. Will break up.

The next morning, Li Mo and all the guests attending the meeting went to Dugu's husband's residence to wait for a visit. When I got there, there were only a few empty houses left, and my father-in-law dugu had disappeared. After learning this anecdote, the people of Yuezhou called on their homes and looked for Zhang Gu everywhere, but they never found him and no one knew his whereabouts.
