Description

The qīnglóng yǎnyuèdāo (青龍偃月刀) or "Green Dragon Crescent Blade" is a mythical polearm wielded by general Guan Yu in the 14th-century historical fiction novel "Romance of the Three Kingdoms".

According to the novel, it was created after the three heroes Liu Bei, Guan Yu and Zhang Fei swore an oath in the peach garden:

"雲長造青龍偃月刀又名冷豔鋸重八十二斤"

"Yun Chang made the "Green Dragon Crescent Blade", also known as the "Cold Brilliant Saw", weighing 82 jin."1

Yun Chang was the courtesy name of Guan Yu.

By the time the Romance of the Three Kingdoms was written, 82 jin weighed approximately 48 kilos. The Han dynasty conversion was about 18 kilos.

The validity of the attribution

It is unlikely that the weapon was actually carried by the historical figure Guan Yu. The yǎnyuèdāo (偃月刀) first occurs in the Song dynasty Wujing Zongyao (武經總要), written almost 1000 years after Guan Yu was alive.2

By the time "Romance of the Three Kingdoms" was written, the weapon was already well-established in military use for three centuries so it probably seemed ancient enough for the author.

Guan Yu as a God of War

Guan Yu was deified as early as the Sui dynasty (581 – 618) as a symbol of loyalty and righteousness. He later became canonized as the God of War, and by the Qing dynasty, as many as 200 temples were erected for him alone that were mostly frequented by soldiers.3 Manchu soldier Dzengseo, who campaigned in the 17th century under Kangxi, mentioned in his diary that they burned incense for his image before going out to war.4

By the 16th-century the weapon was so closely associated with Guan Yu that we find it described as guāndāo (關刀), after Guan Yu.5 Most military writings, however, kept to the name yǎnyuèdāo until the late Qing. In martial arts circles, the weapon is still mostly known as guāndāo today.

Guan's dao in the Purple Cloud Temple?

The Purple Cloud Temple in Wudang has a weapon on display that is being presented as Guan Yu's actual weapon. Another is in the Haizhou Guandi Temple in Shanxi province.

The size and weight, to some, confirm the incredible might of Guan Yu. In reality, visitors are looking at mass-produced Qing dynasty training implements that can be found in museums all over China.

During the Qing dynasty, exceptionally large and yǎnyuèdāo, called wǔkēdāo (武科刀) or "Military Exam Blade" were used for strength training and strength testing.6 In order to pass the exam, each candidate was to perform a simple form with a wǔkēdāo. The standard exam wǔkēdāo was 120 jin or approximately 72 kilos but various other weights were in use for regular training purposes.7
