The hardness of cherry is relatively high, and the scientific name of ironwood is Tie Limu. Tieli wood grows in Sharong County, Guangxi, China, and its hardness is not inferior to steel. This kind of tree is called the iron wood of the "iron wood". Tieli wood is hard and heavy, and it will not rot and deform when it is buried underground or soaked in water for a long time. Therefore, Tieli is often used to build furniture, construction, shipbuilding, bridges and machinery.
Speaking of Tie Limu, it is necessary to mention the Zhenwu Pavilion located in the East People's Park in Rong County. Zhenwu Pavilion is known as the miracle in the history of world architecture. This is because although the pavilion weighs hundreds of tons, it does not need a nail or iron, but a thorough wood structure. Zhenwu Pavilion was built on Beiling Mountain, backed by Xiujiang River, facing Dushan Mountain, surrounded by an ancient embrace, the environment is very elegant. The pavilion is divided into three floors, up to 13 meters high, and it looks very embarrassing. According to historical records, there have been many earthquakes here and several storms have been attacked, but the Zhenwu Pavilion, which has suffered from the disaster, remains unharmed. In 1706, a strong wind pulled up a nearby 10-meter-high flagpole, and the surrounding walls collapsed. Only Zhenwuge was spared. In 1857, the local "earthquakes were heard, the houses were shaken", and the Zhenwu Pavilion remained intact. In 1894, a typhoon swept through and uprooted some large banyan trees next to the pavilion. Several trees were even thrown into the river, and some neighboring houses were also collapsed. The Zhenwu Pavilion is still a good end. Zhenwu Pavilion was built in 1573. It has been more than 400 years since its glory, and it stands tall. This is not only because of its scientific and reasonable structure, but also because it has a good relationship with the fine wood materials. The entire Zhenwu Pavilion has more than 3,000 pieces of wooden components, all of which are made of Tie Limu. Tie Limu is also known as Gemu, or ironwood. It has just been cut down and turned reddish brown. After a long time, it will be black and shiny and dazzling.
In the depths of the jungle in Xishuangbanna, China, an extremely hard and heavy tree named Black Dalbergia is grown. The black rosewood has a dense structure and a staggered texture. It has a black marble-like rose pattern. Its hardness and strength are very large. If you put a piece of rosewood into the water, it will sink to the bottom like a lead.
The crown of "hardest trees" should belong to iron sandalwood (iron birch). The wood of the iron sandalwood can be solid to such a degree that the bullet hits the tree, just like hitting a thick steel plate, and the silk does not move. Its wood is three times harder than oak and twice as hard as ordinary steel, so it can be used as a substitute for steel for the defense industry. Because it is very hard and heavy, it sinks when it enters the water. Even if it is soaked in water for a long time, the inside can be kept dry for a long time. The iron mulberry tree is about 20 meters high, 70 centimeters in diameter, and has a long life of 300-350 years. The bark is dark red or nearly black, with white spots on the top and oval leaves. Its distribution is narrow, only growing in areas bordering North Korea, as well as southern Soviet Union and southern Korea. Iron sandalwood is not only the hardest tree in China, but also the hardest tree in the world.
