Yunda already moved a vast majority of their undergrads to Chenggong years ago like the other campuses. Their international programs and students along with research centers and grad programs have until now remained on the old campus. Would be a huge change if they moved the international programs as well...
Try the Chinese website. It's actually up to date and has some other email addresses like [email protected] along with a booking inquiry form. Like I said, more and more of their clientele are Chinese these days so that's the webpage they keep updated I think.
Last Descents still has active trips on the Nujiang for sure but I think they have been catering more to Chinese clients as of late, which is why the website is out of date. Great company and people though so contact them directly for sure as Dan recommended.
Salvador's weekly organic vegetable delivery which we have used for a long time when we are in Kunming does not come from Haobao but another farm in the same area that Colin has set up the program with. They used to use Haobao but he explained switched because they were raising their prices too high. The farm they use now is I believe the same one that grows all of their organic roma tomatoes. If you'd like more info on the farm itself I'd suggest stopping by Sal's and inquiring.
Peach Taste on the 6th floor of the new Kunming Guangcheng mall at Beijing Lu and Baiyun Lu is quite fantastic for sushi! Very fresh and very well made. My wife and I have been very impressed and became regulars. The place is also always packed so show up early before 6:00 to make a reservation. Sorry don't have the phone number right now.
