I am living in Lijiang and would be open to climbing if I'm free (I don't plan that far in advance, but would probably be free after Jan 1). Feel free to email me - firstname.lastname@example.org.
Just an FYI, Liming is all trad climbing and there isn't the option to rent gear at all. If you are wanting to avoid bringing your own trad gear, I would suggest checking out the Liming Rock Climbing facebook page (https://www.facebook.com/groups/249126188514580/). Maybe you can connect with someone there.
