We Discovered Luoquanya Tiankeng
In the Hanzhong Tiankeng cluster list released in 2016, Luoquanya Tiankeng was not originally included. It was newly added after it was discovered by our expedition team. In an aerial photo provided by Shaanxi Geological Survey Center, by chance we found a spot quite similar to a tiankeng. To verify our suspicion, we arranged an expedition to the spot and that was how Luoquanya Tiankeng was discovered.
