100M handmade? -That is unbelievable. For those that don't know, sunflower seeds are a ubiquitous snack in China. Often you'll see their husks scattered near curbs or in parks, especially where a group of folk have been gathering. A group of old men standing around a chess set, eating sunflower seeds, -that is a Norman Rockwell painting for China. China-ana? If you know a native Chinese person, chances are they have a small divot in the middle of one of their front teeth, caused by cracking the husks of sunflower seeds. BTW, they are delicious. I think they are boiled in a special seasoning, and then dried.
It's especially poignant considering not only China's current transformation, but the fate of these artifacts during the Cultural Revolution.
