“Cultural Differences”?Oh,guys. Are you serious?And why would you make a plastic bag pretend to be a wallet?Last year, the China Internet network information center (cnnic) calculated that the usage rate of mailbox in China was only 38.1%.So why don't you use WeChat?At least 900 million people in China use WeChat.Even without WeChat, there must be a phone?China has 1.3 billion mobile phone users.In addition，In China,Lost-property office won't actively contact owner commonly, because most lose property, do not have identity information, even if have, also confirm very hard is owner himself, because this is inferior to wait for the owner to come back.And with 1.4 billion people in China, of course you have to wait to find the owner.This paper is really full of holes.Luckily,now I understand how is “science” “justified”.
