Torch bearers in the virtual and physical worlds jointly lit up the cauldron at the opening ceremony for the 19th Asian Games in Hangzhou, on September 23.

Over 100 million online torch bearers gathered by the Qiantang River, and they created a tailor-designed digital torch bearer who walked across the river and came to the lotus stadium. It was the first time in the history of the Asian Games that the flame ignition was completed via "digital and real integration."

The opening ceremony used green zero-carbon methanol for the first time. The fuel regenerated from waste carbon was the fuel for the main torch tower, realizing zero emissions and helping create the first carbon-neutral Asian Games. A green, digital and intelligent Asian Games will leave lasting memories for people around the world.
