Stepping into the memorial hall, vintage artifacts such as old firearms, stone millstones that once disguised tunnel entrances, and hand-drawn underground tunnel maps transport visitors back to the fervent era of national resistance. The guide recounts how the people of Ranzhuang, under the Party's leadership, dug a 16-kilometer "Great Wall Underground" with their bare hands—a miracle that allowed everyone present to truly grasp the weight of "wisdom and courage."

Step into the well-preserved original tunnels, crouching to navigate narrow passages that accommodate only one person at a time. Run your hands over the aged bricks worn smooth by time, and peer through hidden observation ports and traps. Immerse yourself in the hardships faced by soldiers and civilians who held their ground in the darkness.

This study tour is more than just a quick visit; it has genuinely integrated the authentic spirit of "bravery, unity, and pragmatism" into the daily lives of Sinotong people. Moving forward, we will carry this red strength forward steadily on our industry path, celebrating the 105th anniversary of the Party's founding with tangible results.
