Stephon Marbury keeps winning in Beijing. Fresh off winning his third championship in the Chinese Basketball Association, Marbury was honored with a postage stamp in a ceremony at the National Museum of China on Saturday.

The 38-year-old left the NBA in 2010 and reinvented himself in China, where he was named one of its 10 “model citizens” in 2014.

Stephon Marbury has a statue in front of the arena, a play based on his life, three Chinese Basketball Association titles and now will have a postage stamp named in his honor in a ceremony Saturday in Beijing, according to the former Knick.

 

“It’s starting to take on a life of its own,’’ Marbury told The Post on Friday.

 

“I’m still trying to wrap my head around the fact that people will be able to buy a stamp of me to mail packages anywhere in the world,’’ said Marbury, who plans to give a speech at the National Museum of China in Beijing. “I am truly humbled. Never did I imagine in all of my 38 years of living that I — a kid who grew up 7,000 miles away from Beijing and a kid who came from the projects of Coney Island — would have a stamp of myself. I can never have dreamed it.”
