On May 22, 2012, Xinhua reprinted an article originally from Beijing Evening News reporting that the Beijing Metropolitan government issued new provisions on public restrooms. According to the new provisions, public restrooms in parks, supermarkets, railroad stations, airports, train stations, and other public places may not be closed before the close of business hours in those places. The number of flies allowed in a public restroom may not exceed two. A toilet blockage must be fixed within 12 hours.
