Of all the weapons in the Romance of the Three Kingdoms novel, Guan Yu’s Green Dragon Blade is probably the most iconic. Guan Yu and his Green Dragon Blade are so closely associated that this kind of blade-on-a-stick weapon is still known in China as the “Guan Dao” (“Dao” means blade). But it is also anachronistic – as far as anyone can tell, this type of weapon did not appear until more than 700 years later in the Song Dynasty. Also they’re not used much in actual battle – they tend to be heavy and were used mainly for strength training.
