Higher incomes have allowed millions of the Chinese to start taking holidays outside their country. At the same time, some Chinese tourists have made headlines recently with annoying behavior. Several tourists have opened the cabin doors of planes to protest against flight delays. Three Chinese tourists were arrested over the weekend for taking nude photos while on holiday in Japan. Chinese authorities, then, have to keep records of their citizens doing anything illegal or inappropriate while in other countries, in an attempt to encourage people to behave while travelling.
