The China World Expo held in Kunming from 65438 to 0999 is a professional exposition with gardening as its theme. There are roughly two types of world expositions, one is called comprehensive world expositions, and strictly speaking, it is called registered world expositions. Expo 20 10, which we bid for this time, is a comprehensive Expo. . The other is called a professional exposition, also known as an approved Expo, which is the kind held in Kunming. The former involves a wide range of contents and a large scale, and the exhibition time often takes five to six months, while the latter exhibits more professional contents, such as ocean, environment, transportation, information, gardening and so on. According to the regulations of the Bureau of International Expositions, starting from 1995, a comprehensive Expo can be held every five years, and a professional Expo can be held once or twice between two comprehensive expositions.
In recent years, the comprehensive world expositions include the 2000 Hanover World Exposition in Germany, the 2005 Aichi World Exposition in Japan and the 10 Shanghai World Exposition.
