The background legend of Dragon Tree:

Mu Guiying, described in the folk song Yang Jiajiang, broke the gate array and stole a dragon tree. A thousand-year-old dragon tree was really found in Shaojin Village, Caishi Town, at the southern foot of Mount Tai.

Its tree is about 17 meters high and its trunk is more than one meter in diameter. Small white flowers bloom in May of the lunar calendar every year, without seeds, and the flowering period is more than 20 days. Its tree is hard, its cross section is filiform and radial, and its branches are extremely difficult to break. Therefore, it is commonly known as the beef tendon tree by locals.

No one knows the exact age of this ancient tree. It is tall and straight, with lush foliage and no withered body.

Although they are not sure that this dragon tree is unique in China, it is very rare.
