Dizi
From Wiki China org cn
The earliest dizi (flute) was made from bone over 7,000 years ago. Most flutes were made of bamboo, which allowed common people to play it. By covering the holes and blowing through the side hole while moving the fingers flexibly between the six holes, a sound will be produced that is leisurely and mellifluous. This always reminds people of a pastoral picture of a farmer riding on an ox while playing a flute.
