In frustration over apparently having never found his match in swordsmanship, Dook Goo Kau Bai buried the four swords that he used over the course of his career in the Sword Tomb atop the mountain near his cave. On the one hand, burying the swords seems to indicate that Dook Goo Kau Bai intended for his legacy to be buried forever. On the other hand, he did leave written comments about each of the swords - how and when he used them, and the reason that he gave each of them up.
As it turned out, at least three great wulin warriors - Yeung Gor, Fung Ching Yeung, and Ling Wu Chung did take up his legacy. Do you think Dook Goo Kau Bai anticipated/counted on something like that happening eventually?
