Bamboo is a highly renewable resource with a short growth cycle. Proper harvesting will not only not damage the ecological environment, but also promote the regeneration of bamboo resources. Bamboo is also one of the fastest-growing plants on the earth. Its maturity period only takes 3-5 years, while it takes decades or even hundreds of years for trees. Bamboo regenerates naturally after being cut down, so there is no need to replant. Bamboo is the Materials can protect the environment, so that green mountains are always there and the cycle continues.

Leaves are also an inexhaustible renewable resource, growing in spring and falling in autumn, and reincarnating naturally, and can be used to make feed, fuel and fertilizer.
