The Mixed-Gold Tang is Wu Tianxi’s signature weapon in the Sui–Tang heroic tradition. Its established name and strong association with Wu Tianxi make it a character-bound Object rather than a generic tang polearm.
Shuo Tang repeatedly calls the weapon 混金鐺, while later storytelling commonly uses forms such as 混金镗 and 混天镋. This Subject uses Mixed-Gold Tang / 混金镗 as the public Canon while preserving the primary-text and storytelling variants as controlled aliases.
This weapon is distinct from Yuwen Chengdu’s Phoenix-Winged Gilded Tang. Phoenix-winged and generic gilded forms belong to that separate canonical identity and are not aliases of Wu Tianxi’s weapon.
