ISU Short Track World Cup: Olympic champion Ren Ziwei marked his return to action at the ISU Short Track World Cup here, ending a hiatus of almost 600 days from international competition.

The 26-year-old was knocked out in the men's 1,500m and 500m (2) quarterfinals and is set to compete in repechages for both events on Saturday, reports Xinhua.

"I felt like I didn't perform well and there were some mistakes, but I am willing to accept my lows, and keep working hard and playing well every day," said Ren.
