Second Taiwan Strait Crisis
The Young Pioneers song is "We are the heirs of communism" (). It was originally the theme song of "Heroic Little Eighth-Routers" (), a 1961 film about the 1958 Second Taiwan Strait Crisis and a real-life group of children who stayed on the frontlines of coastal Fujian in order to help the war effort against Kuomintang forces.
