This is 2019,our chinese local people are quite far more modern than the old moneys. we use wechat instead of emails.ok? if we do some research in your country,left money and namecard and wechat accounts there.I do believe no wallet will be send back.but I know you.what a hell ,full stereotypes and prejudice！extremly ridiculous researchers!don't be angry,you deserve that.science at least lost 20% prestige in China mainland because of you.
