In the history group, the participants sought answers to their questions on the internet, but had no means of judging which version of history was the valid one. They gathered facts and dates through various search engines, but whereas one website ex plained the construction of the Berlin Wall as a way of preventing GDR citi zens from being seduced by Western capitalism, another explained the Wall as the GDRs defense against aggressive Western powers that were stationing Jupiter missiles on German, Italian and Turkish soil, equipped with nuclear heads directed towards Moscow. The Chinese teachers had no idea why Americans would be dancing at the fall of the Berlin Wall in 1989. They were unfamiliar with the history of the Cold War between the United States and the USSR, and they didn't know to what extent the American occupation of West Germany was crucial to understanding the history of the Berlin Wall.
