TO Angela Ho's spanking new gallery located at the California Tower in Lan Kwai Fong for a taste of the wonderful Shanghainese decadence one keeps hearing about. And bohemian artist Sun Lang from across the border does not disappoint. His paintings are as colourful in texture as they are in sexual content. And as I strolled around studying his handiwork I had a sneaking feeling that Sun must at one time have studied to be a gynaecologist, and then switched in midstream to take up art instead. Some of his paintings make such detailed reference to the human reproductive process that in a decade or two these may well be the type of illustrations that enlightened students will be using for easy reference in biology classes. Angela, who chose to open her gallery with Sun's surrealist efforts, remarked that she was ''mightily relieved'' to have moved her workplace from her home on the south side of the island to a central location. And the turnout for the opening cocktail party was a veritable Who's Who of the Hongkong social set. Keeping Posted's art consultant, Phil Clarke, dressed as always like an off-duty archdeacon, was on hand to give his own assessment. ''I can live with any of these paintings,'' he offered, ''unlike some paintings with which I am content merely to have a one-night stand in a gallery.'' (Sorry about that, dear readers, the poor boy must have had rather a stressful day.) It wasn't so much the paintings that interested Norman McLeod, of the AndreNorman crimping team. Having told us all that Angela's new place is situated where his first salon was some years back, the snip and wave artist then strolled purposefully around his old haunt as if he was searching for some curlers or brushes that he may have left behind. Angela's proud dad, casino magnate Stanley Ho, looked in - slightly out of breath as if he'd entered the building through the tradesmen's entrance and had to walk up six floors of stairs. After a few brief minutes, Mr Ho was away, but as he was walking out he paused by the door to point casually to the nearest painting to the exit and tell Angela he'll buy that one if nobody else does. I'm not too sure if he was aware that the painting he had picked featured a shark (a carnivore much in the news of late) although it carried the rather innocuous title Dream Of Water Lily. Anyway, that will be US$6,000 if you don't mind, please, Mr Ho.
