Few people here have clothes dryers, which makes laundry a pretty public affair. Most apartment buildings (with the exception of those in the most affluent areas of the city) have long poles sticking out from each window, for hanging clothes out to dry. It's also common to see clothesline hung up between buildings, trees, or anything else you can affix it to. Shops often have the owners' laundry hanging on the street outside. And, once you've seen someone's underwear, it definitely makes the shopping experience feel more personal.
Here are a few shots of laundry - the first is from an apartment building that we pass on the way to the metro (about a 10 minute walk from our place.) The second is from our trip to Suzhou. And, the third is our own washing set-up: the washing machine and drying rack are in the corner of our bathroom.
Given the environmental impact of dryers and China's population of over a billion, this is probably a good thing. And, given how simple it is to hang things, I hope to be better about doing so even after we have access to a dryer again.
