There’s a peculiarly Chinese form of accelerated entropy. The moment anything is built by China’s vast army of manual labourers, it begins a rapid descent into a state of grimy disrepair. Meanwhile many urban citizens live provisional, precarious and strangely rural lives under the feet of the brand-new high rise ruins whose interiors they’ll never see. The cities of China have grown up fast, but the other part of the deal is that they plan to fall down again the moment everyone’s backs are turned.
