Introduction to the stone blocks: More than 3,000 huge stones were used to seal the tomb passage, three corridors and doorways of the Queen's Tomb, and the vestibule. The block stones were engraved with the block stone serial number, scale, stem and branch timing, craftsman's name, palace location, construction sequence, and tombs. The inscriptions on parts and scales provide valuable information for the study of calligraphy, characters, calendars, scales and other aspects of the Han Dynasty.
