According to Sixth Tone, Laoximen land clearance and resettlement is scheduled for completion by the end of this year with major works to start after this Chinese New Year. This extremely informative blog has a number of well researched articles on the progressive demise of Shanghai's old neighborhoods, and it's well worth the time for those interested to read them.
I was eagerly planning to revisit some of the neighborhoods with lòngtáng on my forthcoming trip to Shanghai and add to my inventory of candid photography, but was disappointed to read that large areas of Laoximen; one of the most well known of these neighborhoods, are being demolished by the city's government in the name of modernizing the area and raising living standards.
Some of these 'singalong' parlors still exist, faded and tired but otherwise unchanged, offering a taste of popular and cheap entertainment from a past era. How these survive in anyone's guess. The parlors usually have an organist (who can also play a guitar) and a handful of habitual customers who sing Cantonese songs...and occasionally Western oldies such as "Sealed With A Kiss" by the Canton Singing House organist.
Get out there. The only way to discover the rhythm of life in a place, and so figure out what to shoot, is to experience it. Many places, particularly hot ones, are active very early in the morning and late in the afternoon but rather in a lull around midday. Get up early, stay out late. If you are on a tour that is scheduled to leave the hotel or ship at 9:00, get up well before dawn. Wander around before meeting up with your companions. If the tour goes back to the hotel or ship for lunch, don't go with them. Rather than take the bus back at the end of an afternoon tour, hang around until after sunset and then take a taxi. Use any spare time to get out and look for photographs. Besides availing yourself of more opportunities, time spent discovering the place will enrich your experience.
Above all, work the situations over. Never be satisfied with your first view of a place or the first frame you snap. It's always possible—and usually likely—that you can come up with something better. Why else would painters make sketches? Get closer, then get closer still. Try different angles, different lenses. Wait for the light, wait for the crowd, wait for a bird to land on the tree branch. Never be in a hurry to get somewhere else. Tell yourself that nothing is more important than getting the best you can get out of the situation you are in. Once you've exhausted every possibility you can think of, you can start working on the next one.
