When I was living in Shanghai there was an anti-Japan period like this sometime in 2004, I'm sure it was worst that time as there were marches to the Japan Embassy, demonstrations and small skirmishes between protestors and police.
In my office that time the most vocal person is a lady who's our Operations Manager and been working with us for a while. She was paid well for Chinese standard by the American company we were working for so obviously her lifestyle is pretty good compared with the normal PRCs. She'll come into office and condemn Japan whole day and day after day. After a few days it got me to irritated that I confronted her (she reports to me) and to;d her off to throw her Sony TVs, Nikon cameras and lens, National aircons etc out of her window is she so 爱国. You see because of her pay she only choose Japanese branded products whenever she can for her home and whenever available imported Japanese products even better. I really shut her up that time for good. She hated me to the core I know. But what the fuck.
