The extant spectrum of Guangling San was first found in the Magic Secret Spectrum (1425) compiled by Zhu Quan in Ming Dynasty, which contained subheadings about stabbing Korea, rushing to the crown, getting angry and reporting swords. Therefore, ancient Qin composers stabbed Guangling San and Nie Zheng to death in korean king. According to Zhao's History of the Three Kingdoms and Cultural Survey, there are 45 pieces in the total score of Guangling San, which are divided into six parts: finger, minor preface, major preface, correct voice, chaotic voice and post-preface. Zheng Zheng used to sympathize with Nie Zheng's unfortunate fate; After the affirmative voice, he expressed his praise and praise for the heroic deeds of Nie Zheng Nie Zheng who stabbed korean king. Positive voice is the main part of music, which shows the emotional development process of Nie Zheng from resentment to indignation, and profoundly depicts his revenge will of not fearing violence and preferring death to surrender. The whole song always runs through the interweaving, ups and downs, development and changes of the two theme tones. One is the theme of correct pronunciation found in the second paragraph of Correct Tone, and the other is the theme of disordered pronunciation that first appears at the end of the grand sequence. Affirmative tone is mostly at the beginning of a paragraph, highlighting its leading role. Chaotic themes are mostly used at the end of paragraphs, which makes all kinds of changing tunes come down to the same tone, which has the function of marking paragraphs and unifying the whole song. The melody of Guangling San is passionate and generous. It is the only existing Guqin music in China with a fighting atmosphere with Mao Ge, which directly expresses the fighting spirit of the oppressed against the tyrant and has high ideological and artistic quality. Perhaps Ji Kang saw the rebellious spirit and fighting will of Guangling San, so he loved Guangling San so much and had such deep feelings for it. Guangling San was a smash hit in the Qing Dynasty. After the founding of People's Republic of China (PRC), Mr Guan Pinghu, a famous guqin musician in China, arranged and played according to the tunes contained in The Magic Secret, which made this wonderful guqin music return to the world. Modern violinists believe that this song originated from the HeJian Zaqu in the series. "Guangling" is the ancient name of Yangzhou, and "three" means exercising and enjoying music. The title of Guangling San shows that it is a kind of piano music popular in ancient Guangling area. This is a large-scale instrumental work in ancient China. Germinated in the Qin and Han Dynasties, its name was first recorded in the book Listening to Guangling Qingsan written by Wei Yingkun and Liu Kongcai. In the Wei and Jin dynasties, it gradually took shape and finalized. Later, it was once lost, and later generations found it in the "Magic Secret Spectrum" of the Ming Dynasty, and then rearranged it to get the "Guangling San" we are hearing now. Qin Le's content is said to tell the story of revenge for his father and assassination of Hanwang during the Warring States Period. Ji Kang is a master of art, and his works, such as Nothing to Worry about, Difficult to Learn Nature, Advice from the Taishi, Mingdan and Relieving Private Health, have been handed down from generation to generation. His piano, especially Guangling San, is remarkable. Ruan Ji, who was thirteen years older than him at that time, was as famous as him. There is often a saying in the history of music that "Qin Qin is Ruan Xiao", but Ji Kang is superior to Ruan Ji in both thought and personality. Ji Kang dismissed the long-standing dogmatic etiquette and hated the filthy and treacherous official career. He would rather be an unknown and free blacksmith outside Luoyang than follow the crowd. He is obsessed with pursuing the lofty realm of life in his heart: getting rid of bondage, releasing humanity, returning to nature and enjoying leisure. Wang Xiong's fire and powerful hammering are wonderful interpretations of this realm. Therefore, when his friend Dan Tao recommended him to be an official in the imperial court, he resolutely broke up with Dan Tao, and wrote the famous "Breaking Up with Mountain Residence" in cultural history to clarify his feelings. Unfortunately, Ji Kang's outstanding talent and carefree lifestyle finally brought him disaster. His life philosophy of "not Tang Wu, but thin Kong Zhou" and "the more famous the teacher, the more natural" deeply hurt the key of the ruling class: Ji Kang despised the classics of sages so much and hated official career. If it goes on for a long time, it will not endanger my peaceful rule. This man can't kill Zhengmin, the king of Qing Dynasty. Isn't there a Lu An case here? If you are involved with him, you can kill him without giving anyone a hand. Then, under the slander and incitement of some villains who hated Ji Kang, in 262 AD, the ruler Si Mazhao ordered Ji Kang to be executed. In Ji Kang's execution ground, 3,000 Thai students wrote to the court, asking Ji Kang for pardon and taking Ji Kang as their teacher. This shows Ji Kang's academic position and personality charm to the society, but this "unreasonable demand" will certainly not be accepted by those in power. Ji Kang's thought at this moment is not that his radiant life is coming to an end, but that there is no successor to a wonderful music. He asked for a piano and played the final "Guangling San" on a high execution platform in front of thousands of people who came to see him off. The sonorous piano sound and mysterious tunes are overwhelming and float into everyone's heart. After the play, Ji Kang calmly poked the beginning, when he was only 39 years old.
