On the final day, visit the Urban Best Practices Area, which offers a stage for cities to show innovative solutions to common urban problems. Shanghai's display includes an environmentally-friendly building featuring traditional Shanghai shikumen-style ventilation systems and a geothermal heat exploitation network. The "Eco-house in Shanghai" aims to achieve zero energy consumption inside the structure. London has built two houses that will not need conventional electricity and water supplies but instead make use of the sun, wind, biotic energy and rainwater. The houses have slanted rooftops covered with plants and solar panels. Eleven windmills on each of the rooftops will bring fresh air into the houses. Restaurant leftovers will be used for power generation. Visitors will be able to see the process of how the leftovers are turned into electricity. After the UBPA, head over to the corporate pavilions in zones D and E; see what vehicles might look like in 2030 at the SAIC-GM Pavilion.

3. Seven-day tour

On the first day, visit the China, Japan and South Korea pavilions, Expo Theme Pavilion, Expo Culture Center.

On the second day, explore Zone B. Saudi Arabia Pavilion features a 1,600-square-meter cinema screen, the largest in the world. Some 150 date palms, which are common in the desert country, will be planted on the roof of the pavilion, which is shaped like a "moon boat" and surrounded by deserts and seas, just like the country. The UAE Pavilion is enveloped by a semi-transparent patterned screen. Based on a simple octagon, one of the simplest and most ancient patterns in Arabic art, the filigree provides shading while also creating a dynamic play of light and shade inside. Nepal Pavilion, which is themed "Tales of Kathmandu City," captures the important historic moments of the capital city and the architecture, art and culture that has developed for more than 2,000 years. The pavilion is in the form of an ancient Buddhist temple, surrounded by traditional Nepalese houses.

Continue on to Spain Pavilion and then France Pavilion. Dubbed the Sensual City, France Pavilion is a simple building with a big French-style garden inside.
