"I like the thousands of miles of snow in Minshan, and it will bloom after the three armies" means that it is more gratifying to step on the thousands of miles of snow in Minshan, and everyone smiles after the Red Army climbs over. This not only shows the optimism of the Red Army soldiers under extremely difficult conditions. It also reflects the yearning and confidence of the Red Army soldiers for a better revolutionary future.
