　　The three-hour-long opening ceremony was visually striking with dazzling lighting, fireworks, costumes and overwhelming music.

　　The extravagant ceremony, featuring 5,800 performers, started with a drum show called "Harmony: Hearts Beating As One", performed by actors with intellectual disabilities.

　　"Individually each drum produces a unique sound, but together each separate sound complements the other to create a unified single chord which expresses the Special Olympics spirit of harmony and embrace, " music director Liu Tong revealed just ahead of the ceremony.

　　"I hope the music can express the Special Olympics' spirit to the world and let all the people be surprised by the talent and courage of the Special Olympics athletes," added Liu.

　　After the drum performance, the gala show was led into four chapters of performance, characterized apiece by the four themes of the Special Olympics spirit, namely courage, sharing, skill and joy.

　　Amid the performance, some of the leading singers, actors and musicians from home and abroad also made the appearance and gave extra sparkle to the absorbing feast at the Shanghai Stadium, performing their masterpieces or interacting with athletes and the audience.
