A two-part series detailing the counterrevolutionary activities and "crimes" perpetrated by the Roman Catholic Mission in China before and after 1949. Both series are incomplete: the first part lacks the opening sheets; the second part lacks at least one sheet, and possibly more at the end.
Due to this, it is impossible to indicate when the series were published, where, by whom, and for what specific purpose. The last evil deed discussed, at the end of part two, dates from July 1965, during the "Four Clean Ups" movement (四清运动). This suggests that the two series were published some time in the mid-1960s.
The names of the foreign missionaries have been identified as far as possibile.

The text reads "Here, I think it is necessary to call people's attention to the fact that the imperialists and their running dogs, the Chinese reactionaries, will not resign themselves to defeat in this land of China. They will continue to gang up against the Chinese people in every possible way. For example, they will smuggle their agents into China to sow dissension and make trouble. That is certain; they will never neglect these activities.... All this we must take fully into account. Just because we have won victory, we must never relax our vigilance against the frenzied plots for revenge by the imperialists and their running dogs. Whoever relaxes vigilance will disarm himself politically and land himself in a passive position." It is taken from the fifth paragraph of Mao Zedong's "Address to the Preparatory Meeting of the New Political Consultative Conference", from 15 June 1949. The full translation can be found here.
