On the two recent occasions I was in Shanghai, I was thrilled by the abundance of candid street photography opportunities that presented themselves in its old neighborhoods. The narrow lanes crisscrossing these neighborhoods are called lòngtáng (弄堂) or alternatively, lilong (里弄), where whole communities live and sometimes work. The Shanghai lòngtáng can either refer to the lanes that its houses face onto, or to a group of houses connected by them.
Oh gosh, that's 36 hours in the air, Hans? Ouch!! I'm counting total transit time -- for example, a flight I almost booked from Amsterdam to Cape Town had a 2 hour hop to Vienna with an 11 hour layover, followed by a 6.5 hour flight to Ethiopia with a 17 hour layover, followed by a 9 hour flight to Cape Town. Total transit = 45+ hours. Pretty rough!
