Dream pen flower is a strange stone located in Sanhuawu, Beihai, Huangshan, and a giant stone pillar rising in a deep valley. The upright part of the lower part of the stone pillar is round and slender, shaped like a pen, and the top is conical, like a brush tip. The stone crevice between the pen and the nib looks more like China's brush. A Gu Song grows on a stone pillar, circling and winding, full of green, like a flower at the top of a brush.
The jade frame in the mountain is even more strange. When did God decide it? If you can spend money in this life, you can write all the poems in the world. (Li Bai)
