     When you arrive at the Shanghai Expo site, the first thing you will see is a huge red building in the ancient

Chinese dougong (斗拱) architectural (建筑的) style. Built according to the concept of "Oriental Crown", the

China Pavilion (展厅) is the largest national pavilion at the Expo.

     Themed "Search of the East", the pavilion is divided into three sections. Footprint of the East on the top

floor shows the change of Chinese cities; a Journey of Wisdom on the second floor, China's four great

inventions-the compass, paper, printing and gunpowder are displayed; and Blossoming (盛开的) City on the

ground floor shows the scenery of future cities.

     Take a lift, and you'll be taken to the 8,500-square-meter top floor. There, in a film by Lu Chuan, you'll see

how Chinese cities have changed, especially over the past 30 years. The 10-minute movie is shown in a 600-

seat theater.

     The painting Along the River During Qingming Festival, is considered a national treasure. It describes life

in Bianjing, which is today's Kaifeng in Henan province. More than 1,000 years ago, it was the largest city in

the world. Multimedia technology makes more than 1,500 characters of the painting walk and move along a

100-meter-long wall.

     Four families are chosen from Zhejiang province to show their daily lives. Films of the families and furniture

from the households are exhibited. At the pavilion, you'll get insight into the daily lives of these families at

different periods. The designers believe these will mirror the great changes Zhejiang has seen since China's

reform and opening-up policy in the late 1970s.
