毛泽东 《
六言诗·
给彭德怀同志》 (1935, a six-syllable poem to Peng Dehuai during the Long March):
山高路远坑深,大军纵横驰奔。谁敢横刀立马?唯我彭大将军 (Mountains high, roads long, ravines deep; the grand army races back and forth. Who dares take sword in hand astride his horse? Only my great general Peng). A direct tribute to Peng Dehuai's battlefield courage; the last two lines became one of Mao's most quoted modern couplets.
