Dear Professors,
I don’t think leaving a so-called wallet (actually I think it is a file bag) with email address is an effective way to make this research.
I’m appreciating to see you considered Japan’s social situation but why you didn’t take China’s into consideration?
As we all know, only less than 40% people who always use email in China and we also have police stations in the Main Street.
If you didn’t know these things, please delete your essay from this. If you DO know this things but still do this to insult civil in China , you are responsible for your racism and discrimination in your essay.
