The Beijing Olympic Organizing Committee publicized in early August 2006 that it will sell over 7 million tickets for various sporting events and ceremonies to the general public.[13] The chief of the committee expressed her hopes that all Chinese people would have a chance to come to the games. The committee has, therefore, set low ticket prices so as to encourage the Chinese people to become more involved in the Olympics.
On April 14, 2007, tickets to the general public went on sale through the Beijing Organizing Committee for domestic tickets (which will account for 75% of the sales) and through each nation's NOC for overseas ticket sales.[14] By June 2007, 2.2 million tickets—about a third of the supply volume—had already been sold.[15]

The centerpiece of the 2008 Summer Olympics will be the Beijing National Stadium, nicknamed the "Bird Nest" because of its nest-like skeletal structure.[7] Construction of the venue began on December 24, 2003. The Guangdong Olympic Stadium was originally planned, constructed, and completed in 2001 for the Games, but a decision was made to construct a new stadium in Beijing. Government officials engaged architects worldwide in a design competition. A Swiss firm, Herzog & de Meuron Architekten AG, collaborated with China Architecture Design & Research Group to win the competition. The National Stadium will feature a lattice-like concrete skeleton forming the stadium bowl and will have a seating capacity of 80,000 people. Architects originally described the overall design as resembling a bird's nest with an immense ocular—an opening with a retractable roof over the stadium. However, in 2004, the idea of retractable roof was abandoned for economic and safety reasons. The Beijing National Stadium will be the site of the opening and closing ceremonies, as well as the athletics events and soccer finals. The stadium's designer Ai Weiwei has since withdrawn his support for China's Olympic games, saying "he wants nothing to do with them anymore
