The perilous passes and rushing rapids of the past bore witness to the Red Army’s feat of breaking through adversity, with courage and wisdom as its bridge. Today, bridges span valleys one after another, connecting distant places—and also the lights of countless homes and the everyday lives of ordinary people. Bridges have never merely connected mountains and rivers; they are also the answer of generation after generation of Chinese people to meeting hardships head-on. The international communication documentary The Long March: A Road without End, commemorating the 90th anniversary of the victory of the Red Army's Long March, airs the episode three, The Bridge across the Mountains.
