"The song refers to the style and art-making process of my space painting."

Chen's artwork is part of the New York City Department of Transportation's Seasonal Streets program, which temporarily transforms streets into vibrant public spaces during warm weather when people use them the most.

The Song of Dragon and Flowers was selected by the DoT from about a dozen candidates because of its outstanding visual presentation and the meaningful connection with the historical significance of Doyers Street and its Asian-American heritage.

"The plan sounded crazy, since the busy street had to be blocked from both vehicles and pedestrians while the painting was going on," said Chen, who painted the finishing stokes on July 20.

"It was also challenging personally as I had to paint nonstop to make sure the project was completed on schedule. I could hardly stand up over the last few days, my back was killing me.

"But everyone couldn't have been more excited to see the completed work."
