The Belmont Club on Xi Xinping's purges of the Chinese Communist Party:
The Shuanggui pronounced (SHWANG’-gwei) is the secret police of the Communist Party of China, otherwise known as the Central Commission for Discipline Inspection or CCDI. They don’t arrive with flashing lights and thumping rotors. They just show up and then they take you with them, often forever. And they’ve been hard at work arresting tens of thousands of Chinese communists, torturing them to extract confessions and otherwise rounding up anyone connected with Zhou Yongkang, recently the internal security chief of China and head of its oil industry; one of the most powerful men in China now headed for life imprisonment and secret death.
