It is really called Xifeng concentration camp, located in Xifeng county, 72 kilometers north of Guiyang city, Guizhou province. The Kuomintang called Xifeng concentration camp a "university" and Chongqing Baigongguan prison a "middle school". Why did the Kuomintang choose this prison in Xifeng? It is said that it is to put out the bonfire of the * * * production party; Chiang Kai-shek and Dai Li concentrated their construction here for two reasons. One is that Xifeng is located in the hinterland of central Guizhou, the rear area, between Guiyang and Chongqing, and near the Sichuan-Guizhou highway with convenient transportation. Another reason is that Xifeng is located in the middle of the mountains, with lush trees and hidden terrain. Therefore, the military region not only set up a concentration camp here, but also set up a 16 secret service agency in Xifeng county, including the office of the military command bureau, the secret service technical training course, and the second telecommunications headquarters of the military region. At that time, the population of Xifeng County was only over 2,000, while the number of officers stationed in Xifeng was over15,000, more than seven times that of the local population. From the establishment of1938+0/kloc-0 in June to its revocation in July, 1947, 1220 China party member, patriots, patriotic generals and other political prisoners were imprisoned in a * * * for more than seven years. At that time, in order to cover up the true face of this killing cave, Kuomintang spies tried their best to whitewash the concentration camp: the sign of "Military Committee of the National Government" was hung outside the concentration camp, and the cells where "prisoners" were held were classified as "loyalty, filial piety, benevolence, love, faith, righteousness, harmony and peace". More than 600 of these people were tortured to death, and more than 400 people were unaccounted for, and they were probably taken away by the army. There are less than 100 survivors.
