In particular, The Green Woman with a Paper in Hand is a breakthrough in his painting, says Cheng, as it juxtaposes the image into the imagination, implying a concept behind the image. As a result, his work initiates an international form, which pushes beyond the limits of Abstract Expressionism.

Cheng met Martin for the first time in 2008 while he was the co-curator of the 798 Art Biennale. She did not know that he was a painter at the time, as he was a man of few words. In 2010, he was reintroduced to her and it was only then that she got to know his work. "I prefer to call him a 'research painter' since every work contains extensive research and contemplation. With an average of 30 works each year, he does not produce more work than is necessary," she says.

Wehmer became a practicing painter after receiving his formal art education in Germany. He has received several art awards from the Academy and Art Fund in Europe and has his works exhibited in art fairs and museums, including the Zurich Art Fair, and the Museum in Basel.

He's proficient in art history. Wehmer's knowledge extends to issues of international contemporary art. He is a dedicated painter as well as an art educator. In his role as art lecturer at CDK Hangzhou, a joint program with UDK Berlin, he facilitates art exchange programs between China and Germany.

"The daily life of students is becoming more similar between China and the West," he says. "China moves so fast. It is good for art."
