That's a particular favourite of mine; it's looking up the 284m entrance pitch of Da Keng (lit. 'Big Pit') in Tian Xing. The second pitch, which is only about 30m from the base of the first, is 'only' 215m.

We're currently working on our first club journal, which ought to be ready in time for the China Caves symposium at the RGS and the Hidden Earth conference. 32 colour pages of photos, articles and surveys from Tian Xing, where we've explored what are currently the three deepest caves in China.
Should be around six quid a copy.
