Dragon horn, also known as spirit horn, normal horn, division horn, horn flute, horn drum, or simply horn, is made of horn and tin. Dragon horn made of horns is also commonly known as "horn drum"; Those made of tin are called "tin corners". The origin of the Dragon Horn seems to be to simulate the horn on the ancient battlefield, which was used to command soldiers to give orders. Later, it was absorbed by Taoist priests and legalists into their religious ceremonies and became one of the important musical instruments. In the Taoist classics of the Qing Dynasty, the words of "blowing the horn" were recorded to show the power of the heavenly generals. Taiwan Province Province is a legend. When the Dragon Horn is too old to go out to Hanguguan in the west, the one-horned green ox he rode was bought by the one-horned horn on his head, so when the Dragon Horn blows, it will be earth-shattering and command ghosts and gods; Another said that the Dragon Horn was an important instrument for the Tai Shang Lao Jun to pass a spell on Chen Jinggu, so it can be seen that he was holding the Dragon Horn on the sculpture of the statue of Chen Jinggu in Taiwan Province Province. At present, Taoist priests and mages in Taiwan Province Province summon magic soldiers to guard the altar and protect the ceremony by blowing the Dragon Horn.
Dragon horns made of horns, some made of buffalo horns or yellow horns, generally retain their natural shapes and are slightly curved, but now there are substitutes made of plastic, carving the totem of the Big Dipper on the horns, or adding patterns or characters such as the sun and the moon; The artificial dragon horn made of tin has a large bending angle, and there are also the Big Dipper or Nandou, plus the sun and the moon. In appearance, both of them will be tied with red cloth tape or painted with red paint at the mouthpiece.
Liu Zaitian, an early Taiwan Province folklorist, recorded in his field survey that there was a saying that "Aconitum Road" used horns and "Red Head Road" (Legalist School) used tin horns. But now red-headed Taoist priests, black-headed Taoist priests and magicians of folk beliefs can see the horns.
