In contrast to my last post about the hordes of 'influencers' now on Tibetan highways, I would like to recommend a bunch of guys who are doing the real 'hard yards' in the mountains of south-west China: the Dengtuzi hiking club. Don't know much about them but I came across a bunch of their hiking diary videos on ixigua when looking for recent clips about the Kawka Karpo Kora. These guys have really gone off piste! Their site shows some great hikes in the off the beaten track areas around Meili Xueshan in NW Yunnan - not just the usual Outer Kora. (Runner up prize if you want to see a recent video of some Chinese hikers doing the regular kora - here).
These hikers are going into situations that i would be out of my depth in - hiking up snow and ice slopes at 4500 m to get across ridges - and camping out in emergency shelters on slopes where there is no level ground. They also highlight the pitfalls of trying to retreat from a mountain by following streams/creaks through the thick undergrowth of gullies.
They appear to be based in Yunnan (but registered in Xiamen) and you can also find them on channels such as Weibo and Sohu. Oh, and all their videos are in Chinese only so you might need to get your Pleco translator out for the subtitles!
Enjoy ...
