Next , for Chinese condition ，a wallet of 49 yuan and no important documents such as id card ，Ordinary people will choose to bring it to the public of"lost and found" or forget this thing ,everyone is busy.most people think that there is no important documents lost,just 49yuan,so let it go,its doesn't matter, so please Learn about China's national conditions ,thank u.
