In Crouching Tiger, there are many times where you will be weaponless against a series of armed enemies. This can be extremely dangerous, but there are several ways though this.
Number one, you can still doge moves and land hits after they try a series of combo attacks. So don't think that going unarmed will lead to your death.
Number two, if you can, always make them run towards you, as they have difficulty stopping and starting the attacks.
Number three, most of the time, one or two hits is all it takes to get the upper hand, so if you can manage that, hit them where it counts.
