Cleaning staff wash the outside of the main tower of China Central Television (CCTV), which is also mocked as the "trousers" by local residents in the morning of April 9, 2015. Some think they look like "spider men." This is the first time that CCTV has carried out the inside and outside cleaning for its new building since the construction completed in January 2009. It is reported that the cleaning would cost 500,000 yuan, or up to 81,000 U.S. dollars, and spend 40 days. (Photo/CFP)
