Hong Kong ( CNN ) -- Public toilets in China 's capital are coming under new rules , including `` no more than two flies allowed . '' Other rules for Beijing 's public toilet sanitation and staff include waste collection every half hour and bilingual instructions in English and Chinese , according to state-run China Daily . The new standards , announced Monday by the Beijing Municipal Commission of City Administration and Environment , cover public toilets in parks , tourist areas and hotels , bus stops , train stations , airports , hospitals , shopping malls and supermarkets . Jack Sim , founder of the World Toilet Organization ( WTO ) and whose work has earned him the nickname `` Mr . Toilet , '' suggested a `` No Fly Zone '' would be better . `` If there is one fly , it simply means there are other flies , '' said Sim , adding that the disease-carriers `` breed very fast . '' His Singapore-based WTO , which aims to improve sanitation conditions and toilets around the world , held its last annual summit in November in China 's Hainan province . The problem of sanitation is a worldwide one , with some 2.6 billion people -- or half the developing world 's population -- without access to improved sanitation , according to the United Nations , which recognizes it as a human right . Halving that number is one of the United Nations ' eight Millennium Development Goals for the world to achieve by 2015 . China 's toilet problem -- notorious for a pungent smell -- has hindered tourism growth , Sim said , one of the reasons the Beijing Tourism Administration hosted the World Toilet Summit in 2004 and Hainan , a popular tourist destination , was China 's choice for the last gathering . `` A lot of places in China are rare , so beautiful , but tourism agents can not get people there because there are no proper toilet facilities , '' Sim said , adding that he 's met people who smoke in public toilets just to avoid the smell . The WTO worked with Beijing to set toilet standards before the 2008 Olympics , a `` coming-of-age '' event for China , Sim said , adding that China 's National Tourism Administration now wants the WTO 's World Toilet College involved in training professional cleaners . According to China Daily , Beijing invested 400 million yuan ( $ 57 million ) on public toilets in the four years leading up to the Olympics . `` The toilet cleaner has been treated as an unskilled person but should be treated as a tradesman , a technician , '' Sim said , pointing to the critical need for cleaning public toilets to prevent outbreaks of contagious diseases and viruses like the H1N1 strain of influenza . Proper ventilation was also key , he added . `` If we do n't clean toilets , we pay a lot more , '' Sim said . Officials at the China National Tourism Administration and the Beijing Commission of City Administration and Environment could not be immediately reached .
