Strategy of terror.

It is in 1975 and 1976 especially a the end of 1975, that they begin their strategy of terror.

The 'gang of four' hunted down anybody who, as they said, indulged in gossip. The students of the university were told that they must report their friends, or anybody that they had heard pass any comments. They were interrogated at the university and they had to report. They really instituted what I think had never happened before, a kind of system of spying of people spying on each other.
