Huoshenshan Hospital "Mount Fire God Hospital" is an emergency specialty field hospital, built between 23 January and 2 February 2020, in response to the COVID-19 pandemic in China. The facility is located near Zhiyin Lake in the Caidian District, Wuhan, Hubei, China, next to the Wuhan Workers' Sanatorium, and is designed to treat people with COVID-19. The hospital has run under the jurisdiction and management of the People's Liberation Army since its completion. A second field hospital, Leishenshan Hospital, using the same design, opened on 8 February, A further sixteen other temporary treatment facilities were set up in converted buildings in Wuhan for isolation and treatment of COVID-19 cases. Huoshenshan and Leishenshan hospitals were closed on 15 April after community transmission stopped in China, almost a month after the other temporary facilities had been closed.

Funny, looks like a DNA structure chain.
