As the name implies, Guyang Paulownia is an isolated buttonwood tree growing on the southern slope of Yishan Mountain, which comes from the book Gong Yu: "There are only five-color soil in the palace, feathers in summer, Guyang Paulownia floating on the shore, and pearls and fish are in one." ",which means the buttonwood trees on the south slope of Yishan and the stones on the shore of Surabaya have all served as tributes to King Dayu.
Confucius in the Han Dynasty said: "The sun of Yishan, specially born with tung, plays the piano." Three words "play the piano." , is a good material for making harp.
Ying Shao in the Eastern Han Dynasty also said in "Custom Meaning" that "the phoenix tree was born on the rock of Fuyang, and the southeast sun branch is a piano with elegant sound."
From then on, "Guyangtong" refers to an excellent piano or piano material, just as the seven strings also refer to guqin, and sometimes it is written as Guyangtong or Gudong, engraved on the piano or written in many famous poems.
Ge Hong of the Eastern Jin Dynasty said: "You can't cry without strings; Lonely bamboo in summer, I can't help but spit. "
"Qin Zan" by Li Bai in the Tang Dynasty wrote: "Fuyang is a solitary tung, and the sky bones are raised by stones, the roots are old springs, and the leaves are frost. Broken into green leaves, the emblem sounds. Autumn moon pine, eternal wonder. "
In the Song Dynasty, Wang Anshi wrote the poem "Lonely Tung": "Heaven is dense, and loneliness is several hundred. Ling Xiao is indomitable, humble and polite. Old roots are strong, and the sun is more cloudy. When I think about it tomorrow, I am willing to marry the banjo. "
One of Liu Tang's Western Henan's "Ping Qi Xing": "It is customary to start from the north gate of Hebei, and southern Henan belongs to the Pinglu Army. Around Dongyue, martens and furs replace horses, while in Fuyang, solitary tung cuts corners. "
Tang Li Shangyin's Poem with Five Words and Forty Rhymes on the 2nd of this month: "There are frosty mangosteen, and the fog blows Toarey Yang." Xie Huilian wrote in Song Dynasty's Ode to the Qin that "a lonely tree in the dead is broken into a Qin".
The "Forgetting Taste" piano made by Wei Lei, a master of piano-making in the Tang Dynasty, is also known as "Sun Yang's work, and a skillful craftsman makes an elegant instrument".
At the same time as Wei Lei, Sima Cheng Town, the 12th ancestor of Maoshan Sect of Taoist Shangqing School, wrote a biography of Su Qin, saying: "Tongqin is a plain, and it is also the wood of Xuling in Tongbai Mountain near the sea. At the beginning of its development, it was the essence of the stars, containing the spirit of shaoyang, fertile soil and worshipping yue. Get the spirit of water and stone, cultivate the lofty nature, exhaust the ze and fish, and help the poor and the needy. The roots are deep and secluded, and the hidden signs are scattered. Hundreds of millions of years later, people don't know anything, only the phoenix follows and lives in the shade. God is full of spiritual heirs, and his children are far away. People who inherited their ancestors gathered in the sunshine of Yishan, Lujun, and moved around. Not only because of the anger of the earth, but also because of the different materials, clouds and empty mulberry, different performances in winter and summer, and strange sounds from generation to generation. In the past, Fu Wang was also on earth, and the eight tones were harmonious, all of which were false. He came up with a musical instrument, ready to give it, and made a beautiful instrument out of buttonwood, called' Qin'. "
In this idiom, Yishan refers to Zoucheng, Jining, the hometown of Mencius. Confucius climbed the East Mountain, but he was very small. He climbed Mount Tai, but he was very small in the world. This Dongshan Mountain also refers to Yi Shan. I have been there several times. There is a Taoist temple on the mountain called "Lonely Tongguan". The landform of the whole mountain is particularly strange. The whole mountain has no soil, and it is very big. The note is quoted from Yan Feng's Collection of China's Ancient Notes and Novels in Tang Dynasty, Feng Shiwen Ji Jian: "The natives said: This tung tree is different from ordinary tung trees, and all the mountains originated from the soil, but this mountain is surrounded by huge stones, and all the stones around it are accessible to pedestrians. The mountain is hollow, so Tong is famous, so it is a gift. "
According to records, Wang Yu played music with this piano, and his voice was like a crane, singing and dancing, crisp and pleasing to the ear, but unfortunately, the lonely tung tree in Fuyang was said to have disappeared forever in a skyfire. This is just a legend. It should be because the exquisite musical instruments produced by Fuyang Guyang Dutong were cut down at will, which seriously damaged the natural environment and was finally punished by nature. Guyang Dutong disappeared, and Guyang Dutong became a swan song in the music world.
