Green Dragon Crescent Blade


The Green Dragon Crescent Blade is a legendary weapon wielded by the Chinese general Guan Yu in the 14th-century historical novel Romance of the Three Kingdoms. It is a guandao, a type of traditional Chinese weapon.
It is also sometimes referred to as the Frost Fair Blade, from the idea that during a battle in the snow, the blade continuously had blood on it; the blood froze and made a layer of frost on the blade.

In ''Romance of the Three Kingdoms''

In the 14th-century historical novel Romance of the Three Kingdoms, the blade is forged by a local blacksmith using steel sponsored by Zhang Shiping, a merchant sympathetic to Liu Bei's cause. When Guan Yu meets his end in 219, the blade is given to Pan Zhang by Sun Quan for his role in capturing Guan Yu. During the Battle of Yiling, Guan Yu's son Guan Xing kills Pan Zhang when the latter is stunned by a vision of Guan Yu's spirit. Guan Xing then takes back the Green Dragon Crescent Blade and later passes it down the generations from father to son in the Guan family.

Historical validity

It is highly questionable whether Guan Yu actually wielded the Green Dragon or whether it was merely part of the myths surrounding him. Valid historical texts from his time period made no mention of him or anyone wielding a similar weapon. Because the guandao was known not to be widely used until the Song Dynasty, there is some doubt as to whether the guandao existed during Guan Yu's time. The guandao may not have been very widely used because it was both difficult to wield and heavy. However, this may be due to the legend regarding the weight surrounding the blade, whereas in reality, it was much lighter.
According to, the Green Dragon Crescent Blade was said to weigh 82 catties. During the Eastern Han Dynasty and Three Kingdoms periods, one catty was approximately 220 grams, so 82 catties would have been approximately 18 kilograms. A weapon weighing about 100 pounds, purported to be the Green Dragon Crescent Blade, is on display at the Purple Cloud Temple in China today.

Rumored origins

Legend says that Guan Yu invented the guandao. He had it forged after he met Liu Bei and Zhang Fei but before he made the Oath of the Peach Garden.
The story of the blade was that there was a blacksmith forging the blade when suddenly a green dragon passed by. The dragon was cut up and the body became part of the pieces therefore making the dao a magical weapon.
