Introduction to Yunzhongke: The root material of Yunzhongke is the precious southern yew. The branches are connected with each other, and the dragons are hidden among them, either with their heads hidden or with their tails exposed. They are countless, just like a group of dragons dancing in a lantern. Interspersed, it is like a dragon playing in the clouds, moving clouds and spreading rain, which is festive and auspicious.
