Recently, the Shaanxi Provincial Archaeological Research Institute and other units released the latest archaeological results of the Western Han Emperor Mausoleum Project, which determined that the Jiangcun Tomb was the tomb of Liu Heng, the Emperor Xiaowen of the Western Han Dynasty, and unearthed a han Dynasty gear during the excavation process.
The gear is finely made, the serrations are evenly distributed, and it has a strong sense of traversal. In the era of handicraft manufacturing, making a car and horse accessory that closely resembles modern gears is very rare and full of mystery.
