Shanghai - Multi-language services, tour guides and new signs around the city are just some of the preparations made for the influx of foreign visitors to Expo 2010 Shanghai.

More than 3.5 million foreign tourists are expected to visit the Expo, including those from Japan, Korea, Europe and the United States.

To ease potential language problems, the Shanghai Tourism Bureau and tourism bureaus in the Yangtze River Delta area will share resources with 1,000 tour guides to help visitors. The tourism bureau has also published The Guidebook of Shanghai World Expo and other teaching materials for city guides.
