BEIJING: China's vast migration from rural to urban areas over the past 30 years will be the theme for the first section of the China Pavilion at the 2010 Shanghai World Expo.

The pavilion will have a "core exhibition area" on the top floor, an "experience area" on the second and a "functional area" on the first, Chen Xianjin, deputy director general of the Bureau of Shanghai World Expo Coordination, was quoted as saying by Saturday's Shanghai Daily.

China's achievements in urban development from ancient to modern times will be the core theme of the pavilion.

Visitors will first be taken to the top of the pavilion by elevators which will look like trains carrying China's migrant workers to urban towns, Chen said.

There, visitors will see a film "The Migration of Hundreds of Millions" which will picture the past and present lives of the country's migrant workers.

Other exhibitions on the top floor will showcase the conditions of modern Chinese cities, the wisdom that the ancient Chinese used to tackle urban problems and China's future strategy for urban development.

Paintings by children will illustrate the possible future look of cities.

The "experience area" will feature interactive games which invite visitors to plan Chinese cities. The "functional area" will exhibit new technologies that will contribute to a better life.
