At Huangshan.

This is the sign for Flower Blooming on Brush Tip. The sign maybe is hard to read, I'll transcribe it here:

Also known as Gifted Writing Brush consisting of the brush Peak and a pine tree on its top. Chinese legends relate the brush to the grand ancient Chinese poet Li Bai, who was once fascinated here. Later myriads of poems were composed to praise its beauty, one of which says "A nature made gifted brush paints all the lovely scenes". Brush Peak, 1640m in altitude, is one of the 36 small peaks in Mt. Huangshan.

Formed around 1200 million years ago, the peak takes the shape of a brush point while the body looks like a shaft of a brush. More marvelous on top stands a pine tree like a blooming flower in front of the Brush Peak hes the Brush-holder Peak exactly in the shape of a brush holder. What a fantastic wonder to have the brush and the holder within the same vicinity.
