mongolian desert rock

deep in Inner (!) Mongolian desert i attend a 5 days conference on "sustainable sanitation". actually it was only 4 days, cause the organizer missed to put me and 2 colleagues on the arranged flight. no problem, so i could spend one more day in Beijing with my friends.
but against all odds, it is really really nice out here. its not the multistoreyhouse with dry toilets among those thousand of new development project, and also not the conference opening&closing speaches with "circulareconomywelloffsocietyharmonizenvironmentsocialisticcycle" blablahblah
but meeting all my former chinese colleagues and a lot of old and new international friends & colleagues.
The evenings are getting long and longer...
