Any there any more interesting stories or happenings regarding Lau Bun of Choy Lay Fat?

this one posted in the cts stories thread for example, made me interesed.

"For example, Lau Bun was an assassin for the hop sing tong and was known to carry throwing darts in his shirt pocket, butterfly knives in his waistband, or even a pair of double steel whips. one time-even with eye witnesses- lau bun killed a rat in the dark with one of his throwing darts and precisely hit its target killing the rat. there were eye witnesses, but try telling that story and instead of absorbing the information everyone says thats fantasy, or not real. Why? because they can't say that about their own teachers."
