Torch's design evokes Yangtze River, city wall

In the run-up to the Nanjing Youth Olympic Games in August, the games' torch was shown to the public for the first time in a ceremony at Nanjing Green Expo Garden on Sunday.

It is part of a Youth Olympic Culture Festival for the games that runs from March 22 to 30.

Named The Door of Happiness, the torch is predominantly blue, representing the Yangtze River that runs through the host city Nanjing, designers said.
