Liu Tang Zongyuan's "Preface to the Chorus of the King": "When the axe is at the door of the class, it is strong." Song Ouyang Xiu's Book with Mei: "I played tricks on you yesterday."
[1] Ding, seven or eight poems, recorded today. This is ridiculous, teaching fish to swim. "Lu Ban was a skillful craftsman during the Spring and Autumn Period and the Warring States Period. Until now, people still say that Lu Ban is the granddaddy of carpenters. At that time, there was a craftsman named Shi, and people called him Jiang. He is a native of the capital of Chu, and it is said that his skills are inseparable from those of Lu Ban. How high is his skill? Zhuangzi told a story in Xu Wugui. It is said that this stonemason has a good friend and they often perform together. The friend thinly coated the tip of the nose with white ash, and the craftsman took an axe in his hand and aimed it at the tip of the nose. " "Shua" all of a sudden, he used an axe to sweep away the white ash on the tip of the nose, and the tip of the nose could not even wipe the skin. This shows how capable he is. Therefore, Liu Zongyuan later said that if someone "holds an axe at the gate of Ban and Ying Du" and dares to play tricks with an axe in front of craftsmen in Luban and Ying Du, it will be a bit "strong face", that is, shameless. On one occasion, Mei Zhihuan, a poet of the Ming Dynasty, came to Quarrying to pay tribute to Li Bai. Caishiji is a place where Li Bai, a famous poet in the Tang Dynasty, saw the bright moon in the water in folklore. The bright moon is clear and transparent. He bent down to catch it and fell into the river. Because Li Bai left footprints here, legends abound, leaving many places of interest, such as Li Bais Tomb, Chenxian Pagoda and Moon-catching Pavilion. Therefore, Caishiji has become a tourist attraction. On this day, Mei Zhihuan came to Li Bais Tomb, next to Caishiji Mountain. At first glance, she was greatly dissatisfied. On the rocky mountain, on the grave, wherever you can write in front of the grave, people have left poems. Those articles are all nonsense, but tourists who want to pretend to be elegant are actually questioning Li Bais Tomb, who is known as a poet. What are the faces of those poor poets in front of Li Bai? That's ridiculous! Mei Zhihuan thinks more and more uncomfortable. She wrote a poem with emotion: "A pile of earth is quarried by the river, and Li Bai's name is eternal;" There are poems coming and going, and Lu Ban made a big axe in front of him. The earliest prototype of "teaching students how to play with an axe" is Liu Zongyuan's "Teach others how to play with an axe and save face". "It means that it is cheeky to manipulate the axe in front of Lu Ban. (Ying, another ancient axe hand) satirizes those who overreach themselves and show off their skills in front of experts. Mei Zhihuan mocked the tourists who thought they could write poems, and he was "making a big axe in front of Lu Ban". This sentence was simplified by later generations as "teaching fish to swim". In this way, the idiom "teach fish to swim" has been handed down.
Edit this legend
In Ertianmen of Jue Mountain Scenic Area, there is a cave dedicated to Lu Ban, the ancestor of carpenters. According to the Taoist regulations on the worship of immortals, the ancestor of Zhenwu and the immortal fairy capital enshrined in Jue Mountain are related to eliminating disasters and solving problems, exorcising demons and keeping peace, and have nothing to do with the ancestor of carpenter Lu Ban. It turned out that Jue Mountain was helped by Lu Ban, the founder of the carpenter, at the beginning of its construction. According to legend, the founder of Xuanwu was impressed by the local gentry Wang Tailai through profound Taoism. Wang Tailai promised the founder of Xuanwu that he would live in a newly-built temple when the New Year came. However, it was the twelfth lunar month and it was very cold in winter. In order to fulfill his promise, Wang Tailai took out six barrels of gold and built a temple. The local people joined the team that built the temple. Shepherds drive sheep out of the sheepfold, carry bricks on the mountains and carry large ice cubes in the river. Countless sheep are exhausted in just one day. In a few days, the walls around the temple are basically over, and it's time to fight the arch. Because of the cold weather, the parts of the bucket arch don't stick together at all. The leather glue boiled on the ground was frozen into a knot before it reached the carpenter. The Spring Festival is coming soon, so it is impossible to catch up with the construction period. Mrs. Wang's hair turned white overnight. The next day, he came to the top of Jueshan Mountain, looked at the temple where he was going to climb the archway, and cried bitterly. This cry alarmed the thin old man who was digging a panlong caisson. Before the old man came to Wang Tailai, he heard the supervisor shout, "He has been here for almost a month. I'll give you a piece of wood to dig an algae well. Now you are going to the algae well soon. It is still a piece of wood. Don't worry. " The old man didn't listen to the supervisor and went up to Mrs. Wang and said, "Boss, what are you worried about?" Mrs. Wang poured out her troubles these days. Hearing this, the old man whispered a few words in Mrs. Wang's ear and knocked on the wood alone again. First of all, Mrs. Wang was surprised. After careful consideration, she decided to treat her as a dead horse. Mrs. Wang ordered people to mash the glutinous rice and cook it into a paste, let each craftsman eat a bowl, spit it in his mouth, and stick the spit glutinous rice paste to the bucket arch. This move really worked. In less than a day, all the arches on the mound were glued together. Due to the weather, the glued bucket arch is very strong. Wang Tai came to ask the carpenter this method, and he didn't know why. Time to go to the caisson. Mrs. Wang came to the old man who carved caissons on the construction site, but she couldn't find them. Only the piece of wood he carved is still there. Mrs. Wang came to the wood and shook it gently. She heard a loud noise. On that piece of wood, four dragons appeared at once. Dragon pattern winding, smoking, surrounding the treasure in the middle. Mrs. Wang ordered people to install the caisson carefully. The caisson is not too big or too small, and it is installed just right. He admires the old man's carving skills. Mrs. Wang went home and told her family about it. At the same time, I prayed in front of the ancestral shrine and said, "I have repaired the temple. Please come here in a few days." In the evening, Wang Tailai had a dream. In his dream, he met an old man, who told him to insist on fighting the arch. The old man said to him: "It is not easy to abandon evil and do good, and it is not easy for the founder of Xuanwu to take this as a degree. I am also the founder of the carpenter, Lu Ban. When I learned that my father had difficulty in repairing the temple, I came to help him as a mortal. " Wang Tailai woke up and told the temple keeper about it. The temple keeper is very grateful. Therefore, people dug a grotto in Ertianmen to worship the founder of Luban in order to commemorate his achievements in building the top of Jueshan Mountain. Although, Xuanwu Temple has experienced several generations and has been repaired many times. However, Luban's help in repairing the temple was widely circulated in the local area.
