It is true that Japan has different culture. Japanese Prefer returning it to police station than directly contacting owners. Guess what? CHINA HAS DIFFERENT CULTURE TOOOOOOOOOOOOO!!!
Only a few Chinese use email in their daily life(According to the research on China Internet by government in 2018, more than 60% emails have been abondoned over a year), they prefer WeChat(An communication app like WhatsApp) and phone call. Also more than half Chinese prefer to return it to lost and found place or just wait at the original place in case the owner return back but can’t find his purse.
In what universe can researchers consider Japanese culture but ignore Chinese culture? Especially when both of them are Asia countries. Just like I can’t imagine a research have considered Canada culture but ignored U.S. culture. It is reasonable and logical to doubt the researchers are raciests. Shame on you, Science, for letting racists’ article being published.
