Chapter 7 - Square and Round Describes the drive for education and improvement amongst the factory workers, being met by other enterprising migrants setting up training courses - of variable quality - on the subjects which might provide advancement. One class is being taught by a 17 year old who went out from her village when she was 15, was an assembly worker and is now an educational consultant. Another teacher had been in Donggguan for 22 days. The fierce competition to stand out, combined with the diversity of ways this might happed reminded me, for some reason, of the Cambrian Explosion (described in Wonderful Life ), a large number or random experiments in what was needed to succeed in a competitive environment, with no underlying plan.
