Tiger Bench This is a unique torture in China. The key point of using tiger stool is to let the victim sit in a sitting position (with his arms tied behind his back or tied in a cross), which will increase the tension of leg ligaments, while the supine position will reduce the pain due to the relaxation of hip joint and leg ligaments; The second is the thigh with the leg tied to the knee, not the lower part. Because the role of the tiger stool is to pull the joint ligament of the victim's leg and dislocate the knee joint, instead of breaking the victim's calf. Because it takes a lot of strength to break the calf fibula, the short pain time (the victim fainted quickly) does not meet the requirements of torturers to torture the victim and save their own strength. Make the victim often barefoot, and at the same time torture her ankle with a tiger stool. According to historical records, the victim will sweat when sitting on a tiger stool with three bricks, and his knees will be completely dislocated when sitting on five bricks, and people will faint.
