SHANGHAI, China (Reuters) -- China is coming clean about its filthy toilets, first hosting a world toilet summit and now about to hold its first ever toilet exhibition which will lift the lid on new technology.

The World Toilet Expo will run from May 8 to 10 in Shanghai, China's most fashionable city, with some experts going potty about a dial-a-loo phone line people can call to find the nearest public toilet, the Shanghai Daily said on Wednesday.

"It's expected to solve the long-lasting problem that tourists, cab drivers and people unfamiliar with the city cannot find a toilet when they need one," Han Yurong, a Shanghai Public Sanitation Bureau official, was quoted by state media as saying.
