Ciduad Juarez is dusty and chill. In the long sunlight of the middle of November I stand in the courtyard to warm myself. Behind a chain link fence topped with razor wire a small canal separates the yard from the street beyond and the houses that line it. The canal is built of cinder block, and the water that runs through it is a trickle winding its way through piles of leaves and rubbish. Off to the right it continues out of sight, running between the road and this strange strip of quiet land, behind factories and hotels. Left it ducks behind the concrete building I have emerged from and continues on to the main road, disappearing beneath it into a culvert.

The break yard has several beat up office chairs, two dusty concrete benches, and the remnants of someone’s lunch, a crumpled wrapper and a can of soda. In the lazy afternoon light it looks deserted for decades rather than hours.

Yangzhou looks like a Chinese city. The generalization is a particular one, born of identical train stations, hotels, party buildings and apartment blocks. The first groups of these towers, built five years ago, have terraces and are six stories high, walk ups with nice gardens now slowly being converted into parking. Row upon row of these, identical, were built all over China before each tenant had an automobile or aspired to one. The ponds were initially stocked with koi, a few of which remain. The leaves on the landscaped shrubs and trees are covered with the dirt that settles the air, coal dust carried for miles. Balconies likewise, which remind me of mine in Shanghai that had to be cleaned weekly to be habitable. The sidewalks that wind beside the buildings in each of these complexes are almost completely parked over with VW’s and Audi’s, Buick’s and local brands, mostly black, mostly sedans. This is a Chinese city in two thousand twelve, new towers, new subways, new streets still rising while the old wear fast.

Yangzhou looks familiar after passing Wuxi, Suzhou, Changzhou, Zhenjiang on the train. I am here on a Friday morning, my second trip in a week. Across the Yangtze on a ferry from Zhenjiang, Yangzhou was probably a unique place when I first moved to this country.

These are the cities of accident. They are places I never intended to visit, let alone return to. They have renown spots and local problems, neither of which I will spend much time on. Instead I will visit rooms of concrete where large numbers of people gather to make physical objects for humans they will never meet. It is an odd trade at this level, the view of globalization both immediately present and impossible to understand, far beyond the horizon.

In the late summer the courtyard in Juarez has been spruced up, flowering trees and new chairs. Some space has been cleared beneath the largest tree for the lunch table, which looks both more recently wiped and more regularly used. The air still has the desert’s distinct dryness and the sun lurks overhead, ready to subordinate those out of doors too long. I am happy to see the changes, the growth that is born of daily efforts to improve rather than sudden wealth and dictated construction.

I wonder what Yangzhou will look like when I see it next. I do not know when that will be.  No matter the date there will not, I suspect, have been a change as great as that from bicycle to car, of a million people suddenly learning to drive. As far as China goes my time there was perfect, coincided with the wave. All else is bonus, extra time on set.

The ferry was a gift today, I tell myself in the mirror of the G train back to Shanghai. Until this week I had never been on a boat on the Yangtze. I had never been on a working boat in China, nor had it been on my list.

Sometimes the road, rather than the destination, is the day’s gift. Flowers in the Juarez break yard, road crews building by hand in Yangzhou. These are cities I am lucky to see, to know, and to watch change, even if only small patches in brief moments of time alone.
