Zhang is one of Liu's favorite artists. "I try to participate in the bidding process whenever outstanding pieces by Zhang emerge on the market, and through the years, I have managed to collect his paintings representing almost every major period of his creative career," he says.

Half of the artworks on show are from Rong Bao Zhai and the other half from the Long Museum, with both stating that they are presenting a carefully selected collection of the finest, most representative and important creations by the two artists.

A significant part of the artworks is being shown to the public for the first time, Liu says.
