I felt a Proustian moment of recognition as we approached Zeng Fanzhi’s studio.   I had been here before.   I had.   I visited with Fabien Fryns, who also brought him on a private visit to the RA.   He’s got an unusually developed interest in the history of art and since my last visit has acquired a wonderful Caspar David Friedrich drawing, two Morandis and an Egon Schiele.   He’s in the process of designing a museum for the exhibition of his own and other people’s work.   It’s being designed by Tadao Ando.
