Practitioners of Falun Gong (a qigong meditation focused on moral philosophy, energetic exercises, breathing and promoting living in harmony) were perceived as a threat by the Chinese communist regime.
Since 1999 members were thrown into “re-education through labor” camps where they either renounced their beliefs or became the victims of torture, organ harvesting and execution.
Apart from forcing prisoners to lay face down in snow, throwing buckets of water on them in -20° environments, and having them stand almost naked in winter for 12 hour periods, Exposure (also known as freezing torture) had been the governments favored form of persecution.
In one instance a woman on hunger strike, was chained to a tree in winter. They returned the next day to find an icicle forming from her nose down to her feet.
As of 2009 it’s estimated that at least 2,000 members had been tortured to death.
