A Study on the Dagger-axe of the Wucheng Produced in the 14th Year of Xiaocheng Wang in Zhao Kingdom
연하도소출조국십사년무성과고
Analyzed from the features of the inscriptions, the ge (dagger-axe) of the Wucheng which is collected by the National Museum of China is closely relevant to Zhao States of the Three-Jin area in the Warring-States Period. It is more rational to believe that the manufacture time of the weapon should be 252 BC. The author argues that the name of supervisor is Mangzao (芒早 ), and the position of the main fabricant is Gongshisefu (工師嗇夫 ).
