...... Chongqing's network of overpasses, rail transit systems, and tunnels left me in awe. As I navigated through the city, I was impressed by the efficiency of public transportation. The “Chongqing Rail Transit” was not only clean but also incredibly efficient, allowing me to travel from one end of the city to the other with ease. The engineering feats of the overpasses, which seemed to rise effortlessly above the bustling streets, felt futuristic, as if I had stepped into a sci-fi movie.
