Introduction to the Iron-Armored Tree: The Iron-Armored Tree in the park is a thousand-year-old tree, so the tree grows extremely slowly. The wood is as hard as iron. There are many sharp thorns on the edges of the leaves, which resemble the armor worn by ancient generals, so it is called the Iron-Armored Tree. The tree is about 20 meters high, with a thick and straight trunk and a large and abundant crown. Such a large armored tree is rare in the world. Residents near and far call it a sacred tree and build temples to worship it.
