Cycling gold medalists' helmets take the spotlight

As Chinese female track cyclists Gong Jinjie and Zhong Tianshi ducked their heads and sprinted to their history-making gold medal in the Olympic Velodrome in Rio de Janeiro, the faces of Peking Opera characters painted on their helmets also came into the spotlight for millions of spectators and viewers.

Zhang Dongliang, designer of the helmets, had a sleepless night watching the race on TV at his home in Guangzhou, Guangdong province.

"I feel as if I won the Olympic gold medal myself," Zhang wrote in a post on the mobile messaging app WeChat, below a photo of the two cyclists sprinting toward the finish line.
