We thought we might want to start your day in tiao pi, or silly, mode. And here it is — a classic Line 13 shot of — two arrows for one direction — that's Dongzhimen.

Given, the Beijing Subway does seem to throw some of the craziest signage around. But most likely, this sign at a station in the western part of the line probably signifies that the underground cross-platform passageway has two "holes" to get you to the Dongzhimen-bound platform — much like the average across-the-street underpass downtown.

Which way to Dongzhimen? Your guess is about as good as mine...
