hi阿昆达
I want to make up a story about the alive professor's attitude towards east german. When people are asking them:"Why choose to be east?/…" They only answer in silence. Maybe the political attitude is hard for olds to change, and east German still exist?
People sometimes have an urge to be together to resist foreigns, difficulties,… that is said to be right side; when people are sick of their old group, or when generations are born and they are different to their parents, that is left side.
finally, about the split of world now, that is North and south, the 38 degree latitude line from Korea to Taiwan to ……, I would say east German still counts, hardly heard from germans, and they kind of like right, communism, recently. Since Chinese students are getting to their country, and always know some Germans come to China, Japan (still a split island)
