City of Socks DATANG, China - You probably have never heard of this factory town in coastal China, and there is no reason why you should have. But it fills your sock drawer. Datang produces an astounding nine billion pairs of socks each year - more than one set for every person on the planet. People here fondly call it Socks City, and its annual socks festival attracts 100,000 buyers from around the world.
I have no idea how many cylinders these socks have.
