Firstly, there is little use of e-mails in China, and more people use telephone or wechat. Secondly, there is a deviation in the definition of wallet, that is, most Chinese people don't think it is a wallet and it is important. Thirdly, Chinese people think that wallet conuld be handed over to the police or relevant staff, and many places have lost and found such places, waiting for the owner to find it back. It is not for the staff to contact the owner on their own initiative.But it should be regard as civic honesty.Last but not least,there are may be more misunderstanding of many other countries.
