And after years of living with migrants and working with them and just really doing everything that they were doing, I started piecing all these data points together -- from the things that seem random, like me selling dumplings, to the things that were more obvious, like tracking how much they were spending on their cell phone bills.
Après des années à vivre et travailler avec les ambulants, à travailler et faire tout ce qu'ils faisaient, j'ai commencé à joindre toutes ces données ensemble - des choses à priori insignifiantes comme la vente de raviolis chinois aux choses plus consistantes comme le montant de leurs factures de téléphone.
