A view of a manhole cover near the Kwun Yam Temple in Hong Kong's Hung Hom district, leading to a network of sewers connected to the Hong Kong Polytechnic University (PolyU) in Hong Kong, China, September 29, 2020. Hundreds of protesters trapped during the siege of PolyU last November used this network of sewers to escape, which volunteers like Dave, a diver, helped scout out. Picture taken September 29, 2020.
