The spectacle brought 37,000 naturalists last year.

Roads to the oceanfront meander through desolate kilometers of shipyards and fish farms. They're lined with abandoned boats. Marooned ghost ships, the absence of residents and the mist, all conspire to create an otherworldly ambiance.

The ocean swarms with seafood made delectable by the cold.

And the Yalu River that empties into the sea brims with some 88 fish species.

Demand for the local Shenxian-yuan baijiu (Chinese white liquor) springs from Dandong's water quality. Visitors to the AAAA-rated Tianqiao Gully National Forest Park can tour its plant, where the spirit is made using traditional processes in ancient-style buildings at the foot of the mountain range.

The location is touted as an "oxygen bar" nurtured by the exhalations of bonsai-like maples that cling to crags and entice autumn crowds. Some locals say that chain smokers don't cough there.

It was preserved as the Qing Dynasty (1644-1911) imperial hunting grounds. Ski runs and a lodge were completed a year ago.

Rustic farmhouses exude cornfields as they clamber up slopes and pack the cracks between peaks.

It's a similar panorama at the Fenghuang, or Phoenix, Mountain, where hillside hamlets prelude protruding peaks clutched by gnarled pines punctuated by ancient edifices.

Ecology encounters history at Fenghuang, whose appellation hails from a legend involving Tang Dynasty (AD 618-907) emperor Li Shimin.

The highlands were known as the Black Bone or the Bear Mountains until a general saw an owl swoop from a cave－an ominous omen. So the emperor visited. He instead saw two phoenixes flutter from the cavern－an auspicious totem.
