"249亿像素上海外滩"(249 yi xiang su shang hai wai tan) refered to a photo which claimed to have 24.9 billion pixels about The Bund. It became popular rapidly the moment it appeared on the Internet, February 20, 2016. Careful enough, you would find that in such high-resolution camera nearly everyone had an embarrassing close-up photography.
There was something fleshy on a window of Pudong Shangri-la Hotel. Wow, if you zoomed in, you could make it clear--a naked man was having phone calls keeping the pose that one leg on the window. In addition, among several visitors in the Bund, there was one man pull up his pant in the full glare of publicity.
