Wishing all of them the best, and hopefully the large number heading over will be able to support each other.
The cultural differences I referred to, were more by way of actually
living in China - the day-to-day stuff eg. the radio and television programmes, the packaging of retail goods, the food available, signage, etc - more than the work side of things. In fact, work will
probably provide a certain form of "escape" for them.
Stick with it guys
and Good Luck!
