Thinking for a moment, Li Chang Hu realized he had missed out on something and added, "Of course, I should mention that although you're allowed to pass the methods along to family members or kin by teaching them directly, you can't copy out the contents of the technique and distribute them. Similarly, we can only allow you to browse through the jade slips containing the techniques, and can't allow you to keep them. I hope you don't mind."
Hearing this, Di Tou snapped out of his reverie and let out an understanding nod. Naturally something like techniques were a bit like a copyright or a piece of insider information, although there was no way to keep a complete lid on it, as it was natural for people to use this information for their own benefit, at the very least it couldn't be spread rampantly, or else the information would lose value.
