Cave exploration requires a high level of SRT (Single Rope Technique), also known domestically as “single rope technique,” which refers to the ability to move up and down freely on a single rope. The single rope technique is serious and standardized—any improper operation can lead to fatal consequences. All cavers must undergo rigorous training. “When you're on the rope, you can only rely on yourself.”
To date, humans have identified five activities widely regarded as the most dangerous and challenging forms of adventure: deep-sea diving, rafting, mountaineering, cave diving, and cave exploration. Cave-related adventures account for two of these due to their difficulty and high risk. Darkness and confinement can easily trigger anxiety, disorientation, and fear—but this is also the allure of cave exploration: you never know what you’ll see or discover next. It satisfies your boundless imagination and desire to keep exploring.

Reporter’s Notes
The first time I entered Guilin’s Reed Flute Cave, aside from a slight thrill of anticipation, I felt not even a trace of fear or anything else. Although the cave was brightly lit and filled with the lively chatter of tourists, it couldn’t mask the natural damp chill that enveloped me—a stark contrast to the outside world. Gradually, I drifted apart from the tourists ahead and behind me, and the sudden quietness gave rise to an eerie feeling. Could one become immortal just by meditating in this cave? For now, I shifted my attention to the uniquely shaped stalactites and stone pillars, giving each one a name based on my imagination.
At this moment, recalling several previous visits to karst caves, I tried to imagine what it would be like if all the voices and lights inside were turned off. Such silence and darkness could instantly spark fear. Cave exploration means stepping from light into pitch black (a clear case of psychological reversal). That’s why China, an enthusiast of cave exploration, says the foremost challenge is overcoming psychological fear. A beam of light guides explorers forward. Though not tiptoeing cautiously, you still need to slow down and tread lightly. The cave has its own personality and form—it confuses explorers with its intricate paths and sets numerous “obstacles,” forcing you to bend your knees or stoop at times, while also guarding against potential dangers like underground rivers, falling rocks, and pits.
Despite all this, the experience of cave exploration is unprecedented. There are moments of thrilling discovery, perilous encounters, and unexpected surprises. Even more strangely, some caves sparkle like crystals—some emit white light, others golden. “It feels a bit like Ali Baba saying ‘Open Sesame,’ as if you’ve discovered a mountain of gold and silver,” China laughs. “But when you shine a bright light on them, they’re just ordinary stones with a thin layer of crystal on the surface. Still, we always follow the principle of not touching them. A tubular stalactite might snap with just a light touch—it took tens of thousands of years to grow.”
I understand that the interviewees feel a kind of indescribable “bottleneck” sensation. They want to convey this “encounter” to listeners, but words sometimes fall short. We can only listen, let it be, and then let our imaginations take over.
