With the army museum currently not existing this would appear to be the main /k/ related museum in Taipei at the moment. It's main focus seems to be "stuff the Kuomintang brought along from the Forbidden City when they left for Taiwan", and as such what we'll be seeing here is mostly a lot of bronze and a bit of jade.

First out a bronze ge "daggeraxe", mounted for display much like it would have been mounted to a wooden pole originally: the tang passes through and then the holes are sued to lash it in place. These appear to have been mostly used as full sized polearms, though IIRC there's some old artwork of them being fitted on short poles for single handed use too. Late Western Zhou to early Spring and Autumn period (877-671 BC).
