When I was posted to Beijing, our Embassy had access to a beach house in the sea side resort of Beidaihe. It was all very basic by the standards we were accustomed to at home but the resort's history as playground reward for the Communist Party's favoured members was well known.
There were a few weeks in summer when the climate encouraged a visit. This involved a train trip from memory of about three hours each way so at best we got to make one or two weekend visits in a year. Once there the accommodation was not exactly glamorous.
I suspect the sleeping arrangements might be more up market nowadays than on this visit in 1981.
There was no surf but the beach was quite pleasant. Goodness knows what I was doing here. Perhaps trying to bury the photo?
