As a person who spent 3 months travelling in China in the mid 1980s the experiences of these teacher mirrored many of the frustrations and wonderment I had felt 10 years prior. It was a good trip down memory lane and fascinating to be made aware of some aspects of China I had missed/misinterpreted due to culture differences and language barrier. One thing I totally related to was you never get China out of your skin. 40 years on I have an appreciation of things Chinese that only those that have been there would understand.
