The Labor Service Corps of the Japanese Army controlled labor was located in the courtyard once used by the landlord Yu Chunyuan, and the five large tile houses were used as offices, and the labor brigade leader also lived here. In the labor class is the residence of the Chinese translator Li Chuting. There is a detention center near the north gate. The detention center was mainly for Chinese laborers, so people called him "Yamen".
In addition, unidentified pedestrians, those who spread anti-Manchu anti-Japanese speech, those who violated the labor service class regulations and attempted to escape, or pedestrians without certificates were detained here for interrogation if they were discovered.
Laborer Zhao Guanxi provided the fact that the second warehouse of the 731 unit was lost by a piece of clothing in the clothing warehouse, and the Japanese custodian had stolen it from a laborer who was working there, so the laborer was taken to the "fence" of the labor service class for interrogation. It was later revealed that the dress had been stolen by a Japanese employee, but the laborer was not released. It was not until the day before the 731 unit members escaped that the laborer took advantage of the chaos to escape. His hair was long and long, and people were a little unrecognizable.
The laborers did not cover their bodies at night in the summer and could not wear cotton clothes and shoes in the winter. According to laborer Bai Wubin, "In winter, whenever there is a lunch break, I can only move in the mat shed, and each person holds a lunch box. While eating a cold meal, he stomped his feet to keep warm. In this case many people are frozen. ”
The laborers were dressed in rags and strange ways. Why? It turned out that the 731 unit handed over the clothes left by the dead laborers to the "tailors" and then distributed them to the foreign laborers for wear. According to the tailor Yu Liankui, "The clothes of the laborers are not only tattered, but also have any style, and they are not even washed, and they are repaired with the smell of sweat stains." No matter what kind of cloth, no matter what color, put together for labor to wear. "The laborers wore colorful, zebra-like.
What was particularly serious was that the 731 unit did not care whether the laborers were alive or dead. There was a laborer who had been forcibly recruited from Yushu County, Jilin Province, and one night he suddenly fell seriously ill, and the pain caused him to roll all over the ground, and the Japanese laughed loudly next to him. The laborers begged for help. The Japanese said casually, "Chinese big, it doesn't matter if you're dead." After saying that, he walked away.
For another example, in the spring of 1945, when the wind continued to blow, the tiles of the engineering squad's warehouse were blown off by the wind, and the Japanese ordered the laborer Wang Jiaqing to brave the wind to change the roof tiles. Because the wind was too strong, there was no one on the roof, and the king was forced to climb on the roof, sit on the roof to change the tiles, and a strong wind blew him off the roof and almost fell to his death.
Another year on the "March 9th" day, the Japanese pulled Fang Yonghe and the old locomotive out to go to the boiler room of the power class to replace the shift, but in those days Fang Yonghe was ill and could not push the reels, and Jin Guozhong, a laborer in the original power class, took the initiative to push for him and let him load the furnace ash. By chance, in the middle of the night, the funnel containing the ash residue of the furnace was frozen, and the way to dredge it was to use an iron shovel, and Fang Yonghe fainted on the ground when he was tired. The laborers wanted to send him back, but the Japanese would not allow him until after the morning shift, and did not send Fang Yonghe back to Zhenghuangqi Situn until after the morning shift, but he was unconscious. Because he had no money for medical treatment, he died within a few days.
In 1938, the 731st unit repaired the gravel road, let the laborers dig trenches on both sides of the road, Shao Changhai, who was in the yellow flag ertun, due to his weak physique, desperately could not complete the amount given by the Japanese, so tired that he just wanted to straighten up and breathe, but was found by the Japanese overseer Sadada, leading the wolf dog to Shao Changhai, and went forward to punch and kick and finally let the wolf dog bite him all over his body.
Regarding the situation of the "Yamen", the laborer Bai Wubin also saw some of it, because he was a white iron worker in the works class, and almost all classes went to when repairing the barracks. He had repaired the prison number of "Yamen" and had seen more than a dozen kinds of torture devices such as tiger stools, rubber whips, and beds.
The torture device of the box bed is a poisonous trick that the Japanese came up with, and on each side of a two-meter-long and one-meter-wide wooden board are placed two belt buckles, and a square wooden box with a gap is fixed on the wooden board, and the Japanese give this work to the carpenter Tong Yuchen.
At that time, Tong Yuchen didn't know what this thing was for. Later, the Japanese told him to go to the yamen to repair the doors and windows, and when he heard the screams coming from the next door, he looked for a sound to go, looked through the crack of the half-open door, and was immediately stunned! It turned out that a person was tied to a "box bed", his limbs were tightly locked by a clasp, his head was tightly fastened by a wooden square box, and the Japanese man carrying a water bottle was pouring cold water into the man's mouth along the missing door of Fang Li, pouring it for a while, interrogating it for a while... Tong Yuchen found that this torture device was made by himself. He said regretfully: "You must know that this is a torture device that mutilates our Chinese, and we will not give it to them if we want to die."
