Introduction to the Dragon Robe Tree: Also known as Wannian Wood, it is one of the four largest ironwood trees in China. It is named after the pattern on its trunk that resembles the dragon robe worn by the emperor in ancient times. According to the research of forestry experts, the dragon's robe tree has long been extinct in other parts of the world. There are only a few dragon's robe trees in Shiwanda Mountain. It is a rare tree species unique to Shiwanda Mountain and has been listed as a national first-level protected tree species. People in the mountains come here every first and fifteenth day of the lunar month to pick one or two leaves and put them at the bottom of the box as lucky money, hoping for peace and prosperity.
