When you arrive at the Shanghai Expo site, the first thing you see will be a huge red building in the ancient architectural style.Built according to the concept of “Oriental Crown”, the China Pavilion(展馆)will be the largest national pavilion at the Expo.
Themed “Search of the east”, the three-storey pavilion will be divided into three sections.Footprint of the East on the top floor will illustrate the change of Chinese cities; at Journey of Wisdom on the second, China’s four great inventions—the compass, paper, printing and gun-power will be displayed; and Blossoming(盛开) City on the ground floor will showcase the scenery of future cities.
Fantastic film
Take a lift and you will 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 will be shown in a 600-seat theater.
“It will be like a short epic.The scenery of the work will be like Lord of the Rings.I will shoot the movie in many Chinese cities.Some love stories will be involved,” said Lu.
Grand painting
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 will make more than 1,500 characters of the painting walk and move along a 100-meter-long wall.
Happy families
Four families are chosen from Zhejiang province to show their daily lives.Films of the families and furniture from the households will be exhibited.
At the pavilion, you’ll gain insight into the daily lives of these families at different periods.The designers believe these will mirror the great changes Zhejiang has witnessed since China’s reform and opening-up policy in the late 1970s.
Pick up your camera and upload your videos online, because you may find your work broadcast at the China Pavilion.
The search launched by four websites encourages people to capture and record the rapid development of cities in China and the beauty and the color in people’s lives.Two hundred outstanding entries will be made into films and played on screens at the China Pavilion.
