Introduction to the second exhibition room: The second exhibition room displays the stone coffin tombs in Liuxin Township, Tongshan County and the stone coffin tombs in Qishan, Peixian County. They are both restored and displayed, dating from the late Western Han Dynasty and Wang Mang period respectively. The portrait stone "Anti-Robbers Returning with Honor" inlaid on the wall of the exhibition room is 8 meters long, which is the longest Han Dynasty portrait stone found in China. This portrait stone shows the entire process from interrogating prisoners, releasing prisoners to waiting for the pavilion chief. It is of great significance to the study of the criminal law, torture instruments and waiting system of the Han Dynasty.
