Social credit score - on tour

A Chinese tourist came to visit a foreign country and wants to go back to his home country but during the trip he was found to not have the necessary documents to identify him and the local authorities won't let him go forward until they ask a few question to make sure he is really Chinese. Answers feel 'backwards' but  avoid sounding too Chinese all the time and keep it honest with the local authorities. Try to trike a balance. The aim is to get the most negative score possible.
