"In a few minutes we encounter dramatic proof that China's population is 1.1 billion: At least that many people are in a traffic jam with us. I have never seen a traffic jam like this- a huge, confused, gear-grinding, smoke-spewing, kaleidoscopic mass of vehicles, on the road and on the shoulders, stretching for miles and miles, every single driver simultaneously honking and attempting to change lanes. Our driver, Bill, puts on a wondrous show of skill, boldly bluffing other drivers, displaying lightning reflexes and great courage, aiming for spaces that I would not have attempted in a go-kart. Watching him, we passengers became swept up in the drama, our palms sweating each time he makes another daring, seemingly impossible move that will, if it succeeds, gain us maybe two whole feet. We pass an exciting hour and a half this way, finally arriving at the source of the problem, which is, needless to say, a Repair Crew. Providing security are a half-dozen men who look like police officers or soldiers, standing around smoking and talking, ignoring the crazed traffic roiling past them. The work crew itself consists of eight men, seven of whom are watching one man, who's sitting in the middle of the highway holding a hammer and a chisel. As we inch past, this man is carefully positioning the chisel on a certain spot on the concrete. It takes him a minute or so to get it exactly where he wants it, then, with great care, he raises the hammer and strikes the chisel. I can just barely hear the ping sound over the sound of the honking. The man lifts up the chisel to evaluate the situation. I estimate that, barring unforeseen delays, this particular repair job should easily be completed in 12,000 years. These guys are definitely qualified to do highway repair in the U.S."
