The poem is as follows:Sitting by the pond alone like a tiger who squats, I repose myself under green poplars. If I don’t open my mouth at the awakening of spring, Which insect dare not be silent? Frog is regarded as the king of insects, even comparing favorably with tiger. The frog vision of seeing the world clearly indicates its modesty and ambition. It is the first poem ever written by Mao Zedong, through a tiny frog, Mao Zedong expresses his hero feeling and great ambition completely.
