Cell Introduction: In Zhazidong Concentration Camp, there are 16 men’s cells and two women’s cells. In 2007, when workers were leveling the floor of Female Cell No. 2, they suddenly discovered a hole as big as a bowl, which was located under the beds where revolutionary patriots had slept. In the cave, 2 large iron nails with a length of 8 cm, 4 small iron nails with a length of 5 cm, 3 door bolts, 1 door latch, 1 iron lever, and some unknown iron tools were unearthed. 16 pieces in total. The unearthing of these cultural relics proves the authenticity of the Zhazidong prison break.
