On the morning of April 17, a grand global launch ceremony for the main song of the countdown of 100 days to the Beijing 2008 Olympic Games, "Beijing Welcomes You", was held at the Capital Museum. The song "Beijing Welcomes You" was a collaboration between the Beijing 2008 Olympic Games Organizing Committee, China Mobile Communications Corporation, and the Beijing Municipal Administration of Cultural Heritage. Following the successful release of the one-year countdown theme song for the Beijing 2008 Olympic Games, "We Are Ready," they once again joined forces to invite over a hundred singers from mainland China, Hong Kong, and Taiwan to passionately perform this track. It gathers almost all the popular and powerful vocalists from China's pop music scene. They extend an invitation to the whole world in a special way, warmly embracing guests to the Beijing Olympics through music, and using music to cheer on the Olympics.
