Mascot wins Olympic gold

"Cutting, sewing, embroidering, stuffing cotton, binding... each plush part of the doll is purely handmade. The eyes are crystal and watery, because cardboard paper is added; the nose is translucent with the use of a light coating," Wang says.

Making Bing Dwen Dwen is more complicated than ordinary plush toys. It's the first time for the team to make a stuffed toy with a shell. Speaking of the toy's transparent "coat", Wang says, after more than two months of repeated revisions from proofing to finalization, it was approved by the Organizing Committee of the Winter Olympics.
