The history and origin of the World Expo

[ Edit this paragraph ]

In the ancient farming society, people often carried out trading activities in festivals to celebrate harvests, religious ceremonies and celebrations, and later gradually developed into large-scale trade and exhibition gatherings with regular and fixed places for the purpose of exchanging goods. This is the earliest form of the World Expo. In the 5th century A.D., Persia held the first exhibition that surpassed the market function. In the 18th century, with the continuous emergence of new technologies and products, people gradually thought of holding exhibitions similar to fairs, but only for exhibition and not for sale, with the purpose of publicizing and displaying new products and achievements. In 1791, the Czech Republic held such an exhibition for the first time in the capital Prague. With the progress of science and technology and the development of social productive forces, the scale of the exhibition has gradually expanded, and the geographical scope of the exhibition has expanded from one place to the whole country, from home to abroad, until it has developed into a world-wide exposition with many countries participating.

After World War II, people all over the world rebuilt their homes on the ruined ruins, and on the basis of resuming production and economic recovery, the first post-war World Expo was held in Brussels, Belgium in 1958, with the theme of "Science, Civilization and Humanity".

Its unique and novel shape is still vivid, although it has been nearly half a century. The splendor and richness of the Expo are almost eclipsed by all the previous dock fairs.
