My father suggested that I visit Guilin, apparently a charming city surrounded by world-famous landscapes. Well, in true Chinese style, the city was completely redeveloped in a bland modernist style a couple of years before I got there. Upon my return, I asked my father when he was last in Guilin. The late 1960s, he replied.
I am now somewhat more wary of his China recommendations, paying close attention to when he last visited.
