I was totally shock why this kind of racism and stupid paper would published! Only contains highly Biased data analysis method and ridiculous testing model. When you try to make such a survey in a country, please at least try to figure out what relevant data you should use. Firstly, the editors are totally stupid to use email to reflect so-called “honest”, most of Chinese only use more efficient and popular app such like We-chat. Moreover, when normal people pick up a wallet at hotel or street , them would just give it to the lobby or the police station. Who will send a email to say “ Hey, you lost something come and get???” How does this process even make sense in a 1.6 billion country? And Last But Not Least, WTF of saying that Japanese they are test free because their police station is..??? What are the writers trying to imply???? Totally shit!
