It is a huge self-constructed building covering 4636 square meters,themed'Constructing the Community with a Shared Future for MankindInnovation and Opportunity', making China one of the countries with the largest exhibition areas. The Pavilion is called'Light of China', which symbolizes hope and brightness.展开更多
