There is a wide array of techniques and behaviors around public drying in China – from vegetables and meats, to clothing, to the inventory of a store specializing in calligraphy brushes placed upon a patch of sidewalk in front of the store. Noteworthy drying behaviors aren’t limited to space-constrained urban densities, either – I’ve recently seen stone walls become lettuce drying racks, and odd-length branches in wood piles hung with recently-washed shoes.
Consider the practices that surround drying of different sorts of objects in your context – indoors/private or outdoors/public (and whether that varies by season)? Machine, line or rack (or monkey bars)? What are the infrastructure (built-in or improvised) and customs that support or discourage particular drying behaviors – and to what those behaviors apply? Consider the factors causing that to vary (population density, education, income, electricity access, and so on).
