A precious crown bestowed upon the former Princess Consort (Zhao Xuanzhen's deceased mother) by the Empress Dowager. It is both immensely valuable and a symbol of status and authority within the Prince of Ding's residence. Xiao Yuwan demanded it for herself, causing a major conflict between Zhao Cheng and Zhao Xuanzhen. The crown went missing on the eve of the birthday banquet, which Xiao Yuwan likely orchestrated to sow further discord.
