There are quite a few moves with the pole. IMHO- the analogy of pikes to poles has its limits.
Use of poles was quite common in rivers and bays-boat and barge culture in south China- but the conversion of it to a tool varies with martial styles. Wing chun usage is different from hung ga usage for instance.
Wing chun usage is coordinated with wing chun principles- the devil in the details
thing.
