Launch campaign to make tourists behave properly

In the run-up to the 2008 Olympic Games, on the 11th of every month, tens of thousands of volunteers in Beijing would be dispatched to encourage people to queue up to use public transportation.

Under posters promoting the number 11 (to signify two orderly queues), groups of volunteers formed queues at subway stations for commuters to follow their example. On one such day, Olympians draped in slogan-bearing ribbons thanked passengers for standing in queues at subway stations, while army generals distributed flyers to praise the practice at a bus stop.

The drive was arguably the most successful part of an improvised "good-manner" movement that targeted people behaving in an uncivilized manner. It is one of the most lasting Olympic legacies because orderly queues continue to benefit millions of commuters and shoving and jostling have become a rare sight.
