Heritage sites are precious assets accumulated over time, and once they are impacted by disasters, it is difficult to restore them, and they might even disappear from the earth. This case involves a municipally designated heritage site built during the Qing Dynasty. Due to its old appearance, it underwent renovations. The original roof decorations, Chiaozhi pottery figurines, are estimated to be over 160 years old but were stolen. To prevent further theft of artifacts and effectively enhance the safety of the heritage site and exhibition environment, a project to improve the artifact preservation environment was initiated.
