NAFI2019 achieved a sales volume of just under $1 million, and "presales went much better than expected" this year, he says.

Nanjing's collectors have developed an awareness of new media works' value and appreciate their relatively low prices. This enables new collectors to access top-notch works from the global scene, he explains.

The city's contemporary art scene is undergoing a boom, he says.

A series of new private museums have been opening, and Nanjing has been adopting policies to support galleries.

It also pledged to provide social security and pensions for artists who are ready to move in.

"We set up a special booth at NAFI2020 to introduce the policies and services supporting artists and institutions interested in Nanjing," he says.

"Nanjing is less stressful than Beijing or Shanghai. We have a large number of good universities and art schools here. And its cultural and historical atmosphere has strong appeal, too."
