This has reminded me of an event in the mid 80s, just as China was starting to really modernise and open up.
We were due a visit from a delegation interested in power station equipment and, on the day they arrived, I was a bit late myself, so witnessed their actual arrival. There was a lot of them - two coach-loads. in fact.
I arrived just as the coaches were disembarking, having passed the really quite pleasant Main Office building, a nice Edwardian-style edifice (now demolished).
Having passed the end of that, the coaches stopped and 70 or 80 Chinese engineers got off, able to see the actual factory for the first time.
We knew that the place was not very futuristic or well-maintained, but, seeing it every day did rather make us immune to the actual state of the place.
The Chinese were clearly shocked, stunned and amused at what they saw, lining up for pictures in front of the apparent devastation that was the reality of what had been promoted to them as a world-renowned factory.
They were also amazed to see that we still had air raid shelters.
When you looked it it with fresh eyes, it did look like the end scenes of a war film.
In fact, it was still camouflaged, having been last painted in the 1940s with the free left-over paint from the war.
'They' did have the arrival area cleaned up and painted a little bit less embarrassingly after that, but the rest of it was left to decay steadily.
It's a housing estate now.
