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 possible.

Above, "Sandri (a Frenchman), the chief surgeon of the Catholic Guangci Hospital in Shanghai, had no idea how to operate on a patient. He treated Chinese patients as test subjects and performed the operation based on what he had seen in a book. He even left the patient's damaged kidney behind and wanted to remove it. The patient died within a few days.” (上海天主教广慈医院的外科主任桑德里（法国人），根本不懂得怎样给病人开刀，却把中国病人当作试验品，临时翻书照葫芦画瓢的动手术，竟把病人的坏腰子留下，要腰子割掉，病人不几天就死了).

The Guangci Hospital hospital was founded in 1907 and was formerly known as the Sainte Marie Hospital. It is presently known as the Ruijin Hospital (瑞金医院).

Below, "The Catholic Andang Hospital in Shanghai used Chinese patients as test subjects, and used them to practice dissection after they died. They also sold the bones of the dead for money." (上海天主教安当医院把中国病人当试验品，治死后用来练习解剖，还把死人的骨头拿来卖钱).

Andang Hospital is presently known as Luwan District Central Hospital.
