Apparently, at some Chinese schools, they give all of the students an English name. Kind of like how American schools give you a Spanish name for Spanish class. His name was Adolf. I asked him if he knew any other famous Adolf's. Of course, he did.
I asked him about why the Chinese cheer so fervently against the Americans, even when they're not playing the Chinese. He said it was because Americans were friends with the Japanese. To play devil's advocate, I told him that the Americans fought the Japanese in WW2, significantly helping China, and dropped nukes on the Japanese. He told me it wasn't enough, the US should've eliminated Japan from the map.
I don't think my sample size is representative but I think it's a warning of how strong nationalism can be. In the US, we have relatively free flows of information and we still have a dangerous nationalist movement. I imagine it's much stronger in China where the government actively encourages it.
