Introduction to rattan and bamboo: On the cliffs on both sides of the middle section of the Langma River Valley, there are lush green rattan and bamboo trees growing all over. This kind of bamboo looks like bamboo but not bamboo, like rattan but not rattan: It is said to be bamboo, but it is different from most bamboos. It is flexible and long, like a lingering vine; it is said to be rattan, but each main trunk has bamboo joints. The branches and leaves show the genes of bamboo and are clearly bamboo.
