But what should we do if it smells like chou dofu?

Wow, the word 坏蛋 gets a whole new & exciting meaning.

I have a hard time believing that native Beijingers are bicycling around the capital with a small red anti-terrorist handbook trying to identify explosives.

However the kidnapping advice might come in handy for other situations, like if you're a petitioner from outside of the capital and Beijing authorities are trying to forcibly send you back to the provinces...

Never heard of gunpowder to smell like rotten eggs, esp these days when most projectile propellants probably use a negligible amount of sulfur. Must be the 5,000yr-old Chinese gunpowder recipe that does that that.

Man, the scare mongering running up to "the games" next month is ridiculous...

lol...

All smallish Chinese provision stores in London smell like rottn eggs.Could they be Al Qaeda bomb fatories?!

and if it like a burning-cable, it might be what..?

I think all you guys have problem with logic.
It is mentioned "suspicious item smells like rotten eggs" might be bomb, but it dosnt mean "any item which smells like rotten eggs is the bomb".
Forget the security instructions from NYC after 911 about the bomb, toxit, anthra and gas?
When badmonthing China, illogic knows no boundary.
