What Weapon Does Jackie Chan Use Here inDrunken Master II

Something I've been wondering about lately is whether there's a formal name for the splintered bamboo pole Jackie uses in the Tea Room Fight. I know Jackie has always been great at improvisational weapons, but most of them can be traced back to classic forms. Like ladders are just pole arms with extra steps (ba-dum tis). But I'm at a loss to think of what weapon forms you could train in to even have an idea of how to use something like this effectively. It's like a pole arms, but it's also like a parasol and maybe a whip. I just don't know how to describe what it does. Does this kind of weapon have a formal name, or was this something invented by Jackie Chan and no one ever thought to expand on it on other movies or in real life?
