The victory of the October Revolution in Russia in 1917 awakened the enthusiasm of advanced Chinese intellectuals to master the Russian revolutionary experience, and many young Chinese revolutionaries sought to study directly in the birthplace of October. In order to study Russian revolutionary theory and experience and achieve the goal of transforming the country, it was necessary to train a group of Russian-speaking cadres for the future revolution. The article deals with the history of the first cadre school of the Communist Party of China, the School of Foreign Languages in Yuyangli, a neighborhood of Shanghai. The research shows that, although it existed for only about a year, this school made an important contribution to the education of the first cadres of the CPC and to the development of the Chinese revolution. Its teachers and students vigorously propagated Marxism, actively participated in party construction, led the Chinese workers, peasants, youth, women’s movements and armed struggle. They played a special role in connecting Marxist theory with the practice of the Chinese revolution, developing and strengthening the Party’s organizational strength and expanding its political influence. Old Yuyangli and New Yuyangli are two neighboring streets. In 1920, it was here that a group of Chinese communists in Shanghai established the School of Foreign Languages, which actually became a school for training Chinese revolutionary cadres. The first group of young communists who studied here were sent to the USSR after only a few months of Russian language and political training. Upon returning home, most of the graduates of the School of Foreign Languages became prominent fi gures of the Chinese revolution. The spread of Marxism in China is closely connected with this group of young people who studied in the USSR. Yuyangli is not just a toponym and a place where the School of Foreign Languages was located, but it is a historical “witness” of the CPC’s more than century-long struggle for its ideals.
