Prague has a small communist museum. The main entrance of the museum is three words "Dream, Reality, Nightmare". These three words have already explained the intention of the museum. The Czech Republic is a country experiencing hardships, unlike the Western European revolutions in which workers and peasants are the main subjects. More revolutionary subjects in Eastern Europe were young students. In World War II, Britain, France and Germany held a meeting, saying that we had no opinion on Germany robbing Czech land. The Czech Republic did not know what happened, and the territory was occupied the next day; Later in the Cold War, the "Prague Spring" occurred, Czech students took to the streets to demand freedom from Soviet control, the Soviet Union occupied Prague with a fighter jet per minute. The president, prime minister, and secretary of the country were all captured in Moscow. The Czech leader was soft that day, saying, Big brother, Rao Xiaodi's life, the big brother's punishment is right, we are not making trouble. Germany has a mouth, the Soviet Union has a whirlwind leg. These small Eastern European countries are really miserable [embarrassment]
