The treasure box was then handed over to Xu Chaoying, a research fellow of the ancient architecture department of the museum, marking the official start of renovation work at the former residence and office of eight Qing Dynasty (1644-1911) emperors.
Built in 1537, the Hall of Mental Cultivation was reconstructed during the Emperor Yongzheng's reign (1723-1735), and after that, the chamber was moved to its rear halls. The front halls then became the offices where the emperor handled routine state affairs, reviewed memoranda and received his officials.

Colorfully painted patterns of the azure dragon can be clearly seen on the surface of the box, with the inscription of the "the sixth year of Emperor Jiaqing's reign (1801)."

The main architectural structures in the Forbidden City all have treasure boxes, which were placed in the ridge cylinder in the center of the main ridge on the roof as an item for suppressing evil. During ancient times, placement of the treasure box featured a grand ceremony to pray for safety.
About 30 treasure boxes have been found in various halls and palaces such as the Hall of Supreme Harmony (Taihe Dian), Palace of Gathered Elegance (Chuxiu Gong) and Palace of Earthly Honor (Yikun Gong).
