Soviet aircraft carrier Minsk that served the Soviet Navy from 1978, and later the Russian Navy, was decommissioned in 1993. In 1995 the aircraft carrier was sold to a South Korean businessman for only 4.5 million dollars, and later resold to a Chinese company in Shenzhen where it became the enthralling military museum 'Minsk World'.
At this museum you are totally free; you can touch anything and you can walk everywhere you want.
Many erased inscriptions are updated by Chinese people who don't speak Russian, then it becomes a senseless gibberish. But no one cares, the main thing is that letters are Russian.
