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.

Titled "Evidence of the crime of imperialist missionary Li Lujia" (帝国主义传教士李路嘉的罪证), it details the case of Li Lujia (李路嘉, Domenico Luca Capozi, 1899–1991), an Italian Franciscan missionary, accused of engaging in espionage before 1949, and of inciting Catholics after 1949; and of hiding weapons and plotting a revolt. He was arrested in 1951.

Photographs show a letter (as proof of espionage), and security forces searching for hidden weapons in a nunnery.
