The Seven-Rhythm Long March is a seven-character poem, selected from Mao Zedong's poems. This poem was written in 1935 and 10, when Mao Zedong led the Central Red Army across Minshan, and the Long March was coming to an end.
Zhuanlian, along the route of the Red Army's Long March, overlooks two typical mountains, Wuling Mountain and Wumeng Mountain, and depicts two "Long March Maps" of "Leaping over Wuling Mountain" and "Leaping over Wumeng Mountain" point by point. These two sentences describe the Red Army's conquest of mountains.
The Neck Couplet accepted "Ten Thousand Waters of Qian Shan", but the poet still chose two "Long March Maps": "Skillfully crossing Jinsha River" and "Forcibly crossing Dadu River". The rushing Jinsha River water beats the towering cliffs on both sides, and the mountains and rivers are singing for the victory of the Red Army. The Luding Bridge across the Dadu River has no wooden boards, but only 13 iron cables, which makes people look bleak. These two sentences describe the Red Army's conquest of water.
