This kind of tree was once used to make dragon chairs containing gold wire, which has been known as emperor wood for thousands of years.

In the history of our country, there are "four famous trees", namely Nan, Cinnamomum camphora, Catalpa and Zi. Nanmu is the first of the four famous trees, which is very precious. The most precious of the nanmu is "golden nanmu". In ancient times, golden nanmu was exclusive to the royal family and was called "emperor wood". It was mainly used for the construction of royal palaces, the production of furniture, and the emperor's throne "dragon chair". In ancient times, civilians were not allowed to use golden nanmu casually, and if they did, they would be jailed for "exceeding etiquette".

Golden nanamu is called small leaf Zhengnan, because it becomes golden after oxidation and shines golden in the light, just like a tree containing gold, so it is named golden nanmu. In fact, its gold wire is a kind of crystal between wood fibers, which is very fine. When the amount of crystal is large, it will show a golden color. Therefore, the longer the growth time, the greater the amount of crystallization, the better the quality.

In addition to the noble and charming color, the wood of Nanmu is also the best. From ancient times to the present, there has been a saying that "water cannot be immersed, ants cannot be burrowed," which is very hard, corrosion-resistant and insect-proof. Therefore, most of the coffins of ancient emperors were made of gold nanmu, buried in the ground for thousands of years without decay, and were not afraid of moth. There are ancient fine furniture, couches and so on also like to use gold nanmu, because it is not cold in winter, summer is not hot, good touch, so it is highly sought after.

Golden nanmu is mainly distributed in Sichuan, Guizhou, western Hubei and other mountain areas and rural areas, is a unique precious resource in China. Unfortunately, the golden nanmu takes hundreds of years to mature, the growth rate is very slow, and now it is an extremely scarce resource. And the wild golden nanmu is listed as a national second-class protected plant and can not be cut down at will. Nowadays, it can be said that good gold nanmu has a price but no market, and it is difficult to buy it with money.

At present, many farmers plant golden nanmu, but they can't wait for it to become mature in their lifetime, generally as a landscape tree, or as a precious asset left to future generations. Readers, have you ever seen this precious "emperor wood"?
