"Old Ironstick" the town's drunken old man, and therefore likely a kungfu master
Tai Guai is New Harmony’s own drunken fool. He carries a pilgrim’s gourd full of strong liquor (from the smell) and an iron walking stick. He has long been a fixture of New Harmony, and even his oddest behavior is tolerated – for the most part. He is a regular at the Mo Jia Tea House, though Shu Lao never invites him.
Tai Guai’s nickname is “Old Ironstick”, and his name roughly translates to that.
