The story begins in 1956, when Chinese people are devoting their revolutionary enthusiasm to the fundamental construction of the new country. Wenli (acted by Jiang Wenli), a pretty mathematics teacher in a primary school, and Tongzhi(acted by Zhang Guoli), a model technician in a heavy machinery factory got married in the 1950s. Their 50-year marriage life witnesses the greatest change of China. Therefore, this story is not only about their fifty years life but also represents the history of the People's Republic of China, which tells about the rough and rugged paths of their marriage in annalistic style.
