Bamboo flute is one of the oldest musical instruments in China. It was called Shu in ancient times. Flute is one of the most distinctive playing instruments in China. In May, 1986 and 16 vertical bone flutes (made of bird limb bones) were excavated at the early Neolithic site in Jia Hu Village, Wuyang County, Henan Province, with a history of more than 8,000 years. For vertical blowing, the sound holes range from five to eight, and most of them are seven-tone flutes, which have roughly the same scale as the China tradition we are familiar with now. Bone flutes are engraved with symbols of equal division next to the sound holes, and some sound holes are perforated, which completely conforms to today's China tune and can still be used to play the folk music Chinese Cabbage. During the period of the Yellow Emperor, that is, about 4000 years ago, a large number of bamboos grew in the Yellow River basin, and bamboo was chosen as the material for making flutes. According to historical records, "The Yellow Emperor asked Ling Lun to chop bamboo in Kunming, cut it down to make a flute and blow it to Feng Ming". Taking bamboo as village material is a great progress in flute making. Bamboo vibrates better than bones, and its pronunciation is crisp. Both kinds of bamboo are easy to process. There were seven kinds of flutes in Qin and Han Dynasties, and two kinds of flutes were invented. Cai Yong, Xunxu and Liang Wudi all made twelve flutes, that is to say, one flute is unified. The flute was called "Qi" in ancient times. Xu Shen's Shuo Wen Jie Zi in Han Dynasty recorded: "flute, seven holes, bamboo flute". 1978 Two bamboo flutes were unearthed from the tomb of Zeng Houyi in Sui County, Hubei Province, and two bamboo flutes were unearthed from the tomb of Han Dynasty at Mawangdui No.3 in Changsha, Hunan Province. The unearthed gnats and the Chinese gnats recorded in ancient books are identical in shape except for a slight difference in length. The unearthed flute is the same as the record, and the word "pool" is written on the bamboo tube in the tomb. It's an ancient bamboo flute. Qi in ancient times was very similar to a flute. It is always said that Qi and flute are the same musical instrument, but there are differences. From the unearthed flutes and flutes, it can be seen that the flute, with 6 holes and closed mouth, can play five tones plus one tone sandhi and is covered all over; Flute, 7 holes, opening, can play seven notes plus two variations, without drawing. During the Warring States period, Qi was one of the main musical instruments for sacrificial ceremonies or banquets, and the flute was also very popular. Qu Yuan's student Song Yu also talked about the southern flute at that time, which is very similar to today's flute.
