Gao Jianli (275 BC - 221 BC), a native of Yan State at the end of the Warring States Period, was the earliest known striker. (Building: String music, similar to guzheng and qin, uses bamboo strikes to make sounds.) Gao Jianli and his friend Jing Ke strike and sing, which is very harmonious. In 227 BC, Jing Ke was ordered by Prince Dan of Yan to go to Qin State to assassinate the King of Qin. Gao Jianli and Prince Dan sent Jing Ke to the Yishui River. Gao Jianli saw off Jing Ke's attack on Zhu, and Jing Ke and Zhu Gao sang "The wind is bleak and the water is cold, and the strong man will never return once he leaves." All the people present were moved.
Jing Ke and another warrior of Yan at that time, Qin Wuyang, served as messengers, and presented the head of the former Qin general Fan Yuqi to the King of Qin and presented a map of the State of Yan to please the King of Qin. In the map, there was a dagger with a highly poisonous poison on it. , ready to stab him to death with a dagger when the King of Qin did not pay attention. Jing Ke said goodbye to Prince Dan and his friends on the shore of Yishui. When he was leaving, Gao Jianli attacked Zhuzhu. Jing Ke sang in a peaceful and generous elegy: "The wind is bleak and the water is cold, and the strong man will never return when he is gone."

First, it is "the sound of changing signs" (change signs, also known as "zhong" in ancient books, which is equivalent to ♯4 in the Chinese musical notation, which is a corresponding high, not an absolute pitch. The syllable of the sign cannot be tested. The change of the sign tone means the change of the sign tone as the main tone, and its effect is due to its mode structure. The text does not mention Huang Zhonglu Gao, which has absolutely nothing to do with the ♯F key, let alone the F key. They are completely two sets of unrelated music theory systems. In addition, the sound of changing sign may only be the sound of changing sign in the scale, not necessarily changing sign tone, and changing sign tone is rarely used. This tone is sad and mournful, and it is appropriate to put on a sad sound.
Later, "returned to the sound of Yu" (Yu is equivalent to 6 in the musical notation, and is also a relative pitch. It is a tone in the middle of an equal tone and a middle tone. In the Yu mode, the main tone of the feather is used to form a scale, or a partial tone is added to form a six-tone or seven-tone scale. The effect it produces is also completely caused by the mode structure. The pitch is not mentioned in the text, and it is also possible that there is only a certain uniform and middle-feather sound. For specific analysis, please refer to the study of its main, upper main, lower middle, subordinate, subordinate, upper middle , the interval relationship between the leading tones (not the A mode in the Western music theory system), the pitch is high, and the voice is impassioned. Jing Ke went to Qin with a determination to die. Later, people used this allusion to express the act of generosity and elegy. There is this allusion in Yu Xin's "Si Gui Ming" in the Northern Dynasty: "As soon as the strong man goes, Yannan has the sadness of attacking the building."
It is a pity that Jing Ke failed (details can be found in "Historical Records: Assassin Biography") King Qin was furious, and immediately sent generals Wang Jian, Wang Ben and their sons to destroy the state of Yan, Yan Prince Dan was killed, and Jing Ke's friend Gao Jianli was forced to flee to Outside Song Zicheng, he worked as a bartender in a tavern and changed his name to Yan Da. Although Gao Jianli has found a place to live, his nostalgia for his homeland and Jing Ke are often not in his heart. Sometimes, in the dead of night, he couldn't help but sing along to express his grief. Of course, what he sang the most was the song of Yi Shui: "The wind is Xiao Xiao Xi Yi Shui Han, the strong man is gone, he will never return." Over time, people know that he is Gao Jianli, the famous teacher of Jian Zhu, of course there is no such thing. Concealed the tyrannical King of Qin.
The King of Qin sent someone to take Gao Jianli to the palace and asked: "Are you a friend of Jing Ke? Jing Ke is dead, why are you still alive?" Gao Jianli replied calmly: "I live to attack Zhu, as long as there is a building to attack, I will Then you can live well." The King of Qin said, "That's good! I can fulfill your wish. Sergeants! Blind his eyes, give him another piece of armor and let him strike." Blind. His eyes are blind, but his heart is very bright. He wants to find an opportunity to avenge the country of Yan, his friend Jing Ke, and himself.

Since then, Gao Jianli has deliberately stepped up his practice of hitting builds, and of course his builds have gotten better. King Qin likes to listen to Jizhu very much, but every time Gao gradually leaves Jizhu, King Qin always asks him to sit under the steps, far away from himself. This is also his vigilance. But over time, King Qin's vigilance relaxed somewhat. Sometimes when he was attacking the building, Gao Jianli felt that King Qin was standing near him, and he could even hear King Qin's breathing. Gao Jianli couldn't hold back the excitement in his heart, he thought to himself: "The time is about to come, we should make all preparations." So he collected heavy lead everywhere. Not long after, he collected several large pieces of lead from the warriors in the palace, weighing about twenty pounds. So he carefully placed the lead blocks in the hollow of the building, which apparently became a heavy weapon. One day, the palace servant said to him: "Get ready, the king is going to enjoy the snow today, and let you go to the palace to attack the building." Gao Jian was nervous and excited. When he was ready, he went with the palace staff.
The King of Qin sat on the large throne and listened to Gao Jianli's attack on the building. After a while, the first emperor asked: "Gao Jianli, why is the sound of building today not as loud as usual?" He slowly approached Gao Jianli, stopped beside him, and said, "Is there any new tunes? Play it for me to listen to." I made a new song in a hurry, I hope the king likes it." It was too late, but it was too late, Gao Jianli suddenly grabbed the lead and hit the King Qin fiercely. Missed the first emperor. After the king of Qin was shocked for a while, he was very angry and ordered Gao Jianli to be hanged and the body burned to vent his anger. People in later generations appreciate Gao Jianli's love for the motherland, loyalty to friendship, courage and fearlessness.
