Chinese billionaire Liu Yiqian was at an art auction when he used his American Express card to buy some art. Some really expensive art. He bought Modigliani's 'Reclining Nude' for $170 million.

Wang Wei, Liu's wife, told the New York Times that he had to use his credit card because paying cash upfront would be difficult.


Now Liu has so many points on his card, his entire family which includes four children and two grandchildren can fly anywhere together.


The purchase got him 422 million American Express points which can be converted to 28 million frequent flyer miles.
