"Sailing the Seas Depends on the Helmsman" (Chinese: 大海航行靠舵手; pinyin: Dàhǎi hángxíng kào duòshǒu), sometimes known as "The Helmsman Sets the Ocean Course",^[1][2] is the English-language title of a popular Chinese Communist Party (CCP) revolutionary song which was written by Wang Shuangyin in 1964. This song was commonly sung by the public, especially Red Guards during the Cultural Revolution (1966–1976) in praise of Mao Zedong Thought and the CCP. Like many revolutionary songs, the single verse of Sailing the Seas Depends on the Helmsman was most often sung repeatedly.
