Bloomberg is quite suspicious of this record-setting Hong Kong sale of the ink painting.”The Grand Snowing Mountainous Jiangnan Landscape.” by Cui Ruzhuo:

An eight-panel series of paintings by Cui Ruzhuo sold for HK$236 million ($30 million) at Poly Auction Hong Kong, setting an auction record for a living Asian artist. […]

“There is certainly an interest in creating a public price level for his artworks, and this appears to be at a price level not really for experienced collectors,” said Johnson Chang, who has been dealing in contemporary Chinese art for 30 years. “This sounds quite unbelievable.”
