Cai Guoqiang set out from Quanzhou in 1980s and stepped onto the international stage. In the past 30 years, he grew up in different cultures on five continents and became an internationally renowned artist.

At the dawn of June 20 15, at the seaside of Yuhui Island, a small fishing village in Quanzhou, with the help and witness of domestic technical experts and hundreds of local villagers, he once again gave the "ladder" as a gift to his 100-year-old grandmother and hometown. A 500-meter-high golden fireworks ladder roared up and talked to the infinite universe.

This is Cai Guoqiang's boyhood dream of looking up at the sky and reaching for the stars. For more than 20 years, he tried and failed all over the world, but he never gave up. Finally, when the "ladder" stood between heaven and earth, all the participants at the scene were moved, as if they had seen a miracle. With the disappearance of fireworks, the audience returned to the world, but the shock of the soul could not be calmed down for a long time.
