St. Petersburg

St. Petersburg. The very name brings to mind some of Russia's greatest poets, writers and composers: Pushkin, Dostoevsky, Tchaikovsky. The 19th century was a golden age for St. Petersburg's wealthy classes. It was a world of ballets and balls, of art and literature, of tea and caviar. The golden age ended with the advent of World War 1. Working people were growing more and more discontented. In 1917, Communism came, promising peace and prosperity. St. Petersburg had become Petrograd in 1914. People wanted a Russian name for their city. Ten years later, the city's name changed again, this time to Leningrad.
一提到圣比得堡，我们就想起许多伟大的俄国诗人，作家，作曲家，例如：普希金，杜斯妥也夫斯基，柴可夫斯基。19世纪是圣比得堡富有阶层的黄金时代。充斥着那个世界的是：芭蕾与舞会，文学和艺术以及茶叶和鱼子酱。 黄金时代伴随着一战的爆发而结束。劳动人民的不满情绪愈发强烈。在1917年，共产主义到来，并承诺带来和平与繁荣。 圣彼得堡于1914年更名为彼得格勒。人民想要用俄文为他们的城市命名。十年后，彼得格勒再次更名列宁格勒。
