Looking back at the peaks from the summit, you really feel the swagger of 'the mighty Wumeng rolls past like mud pellets.'
Tips
history
From 《七律·长征》 by 毛泽东 (Mao Zedong, 1935): '五岭逶迤腾细浪,乌蒙磅礴走泥丸。' 乌蒙 = Wumeng range straddling Yunnan/Guizhou, crossed by the Red Army. The hyperbole shrinks towering ranges into rolling mud pellets.
usage
磅礴 (pángbó) = vast / majestic — not a weight unit. 泥丸 = small mud ball, here metaphorical.
