Jin Sinan is known as the "national wood". Phoebe microphylla in Sichuan is the best nanmu. The national second-class protected tree species are only distributed in a few temples.
It is born in the open forest of valleys at an altitude of 4-18 meters. Extremely resistant to rot, insects and rats do not invade, not cool in winter, not hot in summer, and do not hurt the body, while other hardwoods do not have this excellent characteristic. Jin Sinan's dark wood is an evil spirit, a town house, and has certain medicinal value. Jin Sinan's dark wood is more difficult to find when it is buried underground. It belongs to non-renewable resources, and its beautiful appearance due to natural changes has great potential for appreciation.
