Each Opening Ceremony has a theme selected by the host nation. During the "Parade of Nations", the host country's goal is to represent their cultural identity and to show the world their place in society. For example, in the 2008 Beijing Olympics the theme was “unity”. On May 12, 2008, a devastating earthquake occurred in Sichuan. As the host country, China included a commemoration Yao Ming, a Chinese basketball legend, walk hand-in-hand with Lin Hao, a nine-year-old boy who saved some of his classmates following the earthquake.
