I remember in one scene of Swordsman 3, the Spanish envoy asked a Ming officer a question "Just what is this Jianghu?" and the Chinese officer obviously knows the answer but can't really explain it in words so he simply said "Just wherever us wulin people go in and out, that is JiangHu!"
So just what is Jianghu? How do you define it? Is it a specific place or simply a state of being and mind? Is it so abstract a concept that makes it so hard to explain and define?
