March of the Volunteers ...

March of the Volunteers (義勇軍進行曲) was written by Tian Han in 1934 for a play. The song, with minor alteration, became the theme song of the 1935 patriotic film "Sons and Daughters", a story about an intellectual who leaves to fight in the Second Sino-Japanese War. It was one of many songs that were promoted secretly as part of the anti-Japanese resistance. March of the Volunteers later became the National Anthem of the Peoples' Republic of China.
