The Qingdao Navy Museum is a maritime military museum in the coastal city of Qingdao, East China's Shandong province. Its latest draw card is the retired Long March 1 - China's first domestically made nuclear submarine (as seen in the photo above). Built in 1970, the submarine served in the People's Liberation Army Navy for decades before it was decommissioned in 2016. [Photo/VCG]
