Follow the red footprint. The first visit to the Okayama Mountain was touched by the Jinggangshan revolutionary story and the Jinggangshan spirit. On the Huangyangjie, the guns were heard and the enemy was reported. The Red Army defeated the enemy's four regiments with less than one battalion. This is "firm conviction, hard work, seeking truth from facts, dare to ask new ways, rely on the masses, and be brave in victory." The concrete manifestation of the Jinggangshan spirit. To carry forward the Jinggangshan spirit, we must have a firm letter like the revolutionary predecessors. We should not be afraid of sacrifice, overcome difficulties, and work hard.
