Beijing citizens have been told not to pick their noses, yawn or scratch their heads when talking to foreigners during the Olympics.
They have also been given a list of things not to ask overseas visitors - a list so exhaustive it could make conversation difficult.
Ordinary people have also been given detailed instructions on how to talk to disabled people during the Paralympics.
The booklet advises Beijing people to say to disabled people such things as: 'You're really excellent'
Queuing will also be stressed. Officials want the Chinese people to queue up in lines rather than to barge onto buses and trains as shown above.
Will they also be told not to cough to loudly if the smog in Beijing happens to be heavy?
