Walking on the bridge of Luding Bridge, I can feel the hardships of the Red Army's strong crossing of Luding Bridge. There are few 22 soldiers left. Below is the rolling Dadu River. There are machine guns on the opposite side. It is really hard to imagine how much faith and courage they have at that time. We're not afraid to die, we're walking on it, we're all staggering, we're standing, let alone moving on the steel rope, and we're avoiding machine guns, so we're cherishing the hard-won peace now.
