Two-faced person

Two-faced person (Chinese: 两面人; Pinyin: Liǎng Miàn Rén) is a Chinese political term often used by the Chinese Communist Party (CCP) to describe an official or party member who is either corrupt or ideologically disloyal to the party. Xi Jinping, the current general secretary of the CCP and China's president, has repeatedly said that the Chinese people should "Resolutely fight against two-faced cliques and two faced-persons."
First used in the 1960s, the term began to be used more frequently in the 2010s in response to proponents of Xinjiang independence and critics of China's approach to the Uyghur people.

In 2017 the Cyberspace Administration of China, which administers access to the Internet in China, publicly criticized its former director Lu Wei, calling him "a typical two-faced person (典型的两面人)". 
Since 2017, the term has also been used to refer to Uyghur politicians and celebrities who secretly support Xinjiang independence, and to those criticizing Chinese policies related to the Uyghurs.

Three years prior to this, Zhao had called in the same journal for a crackdown on "two-faced people in government".
