Considering that the Chinese government has infiltrated and spammed other climbing sites, you should understand that there may be some reluctance to respond to your post.

Your SP profile gives no background on you at all and may thus arouse suspicion. I suggest that if you want the best chance of useful replies, you prove something of your background and show some evidence of the authenticity of the motives, methodology and uses of your 'research'.

I'm surprised you would not voluntarily do this in the first place, given the sensitive nature of the subject matter.
