Cao said he saw the popularity of the mascot as not a result of aimless brainstorming, but theoretical and strategic thinking. "In fact, there are basic rules behind aesthetics, and one of them is 'contrast and unity'," Cao said.
"The materials combine rigidity and softness, transparency and opaqueness, black and white. The five colors of the Olympic rings and the 'ice ribbon' all achieve a contrasting unity on a visually aesthetic level. And making it into a series of themed products will also bring a different, tactile experience," he added.
Cao still remembers that on Sept 17, the day when Bing Dwen Dwen, and his Winter Paralympic counterpart, Shuey Rhon Rhon, were unveiled to the world, he couldn't help getting choked up and weeping with joy, when his creation appeared on the huge screen and the crowd stood up to applaud.
"I was so touched seeing that the little bit I did for my country was recognized, and I felt closer to my country because of it," said Cao.
However, Cao didn't forget to suggest to his team members that they shouldn't brag about the achievement. He said for young students in the team, starting at a high point may not be a good thing, as the applause could sometimes be the cause of "deafness".
"We are, of course, very excited. But the road ahead is still very long, and we need to keep working hard and reinventing ourselves," said Cao.
