czystka 用英语:

I purge my in-box every morning.

A former member of Poland’s anti-communist opposition movement and deputy defence minister, Macierewicz is known for his efforts to purge the country’s military intelligence services of communist and Russian influence.

The purge of ​alleged Communists and progressives had ​started as early as ​April.

No such purge had been seen in over a century.

One student says the purge is still going on in China and terror is widespread.
