Who invented the guzheng?

Xiaojun's favorite role in the play is Wei Zi. Because Wei Zi likes playing the guzheng, she likes it and learns how to play it. Just because I like Wei Zi, I flaunt Gege every time I get tired of practicing the piano, so that she can improve her interest. After constant persistence and hard work, I finally made a small achievement and played brilliantly. Princess Zhu Huan is on TV recently, and you watch it occasionally. He was very happy when he saw Wei Zi playing the piano. He looked at it carefully with a pious expression and whispered to the tune. After that, he turned to me and asked, "Mom, are people monkeys?" Who invented the guzheng? "Oh, I was really stumped by her. Yes, it is said that people are monkeys, so who first created such a beautiful voice of guzheng? How are those beautiful music played step by step? Such a profound question suddenly appeared, and I didn't know how to answer it. " The foreigner was singing five, five, ... "She hummed the score of Nanniwan she was learning in English, and I stopped at once." No, no, music has no nationality. It is pronounced by the arrival of a microphone, but China is used to using notation, while foreigners are used to using staff. "I use the thin knowledge I know to explain, because I don't know much about music, and I don't even know the basic common sense. I can only reason from the superficial level. At this time, I realized the importance of knowledge, but I can't mislead because of my ignorance! " Oh, I see. "I pretend to understand if you are thoughtful, but I am particularly afraid to ask these difficult questions again." Mom, what about the mermaid? Is there really a mermaid? ""No, mermaids are just characters in fairy tales. She looks like a beautiful face, but her body is a fish. " "Didn't you say that people may be fish? "Oh, by the way, I have seen such a report on the Internet and told her. This time, people contacted again. Can you imagine a mermaid as an undeveloped fish or a human being? I really dare not talk nonsense any more, but I have to say, "this problem will have to be studied slowly when you grow up!" ""When people heard this, they fell to sleep.
