【正确答案】The Red Stone Gorge in Yulin, Shaanxi
"In Yulin, there are two sites you should definitely visit. One is Zhenbei Tower and the other is the Red Stone Gorge. The Red Stone Gorge is so famous that camera crews go there specially to make films!" Two locals told us on a long-distance bus to Yulin.
Such being the case, we'll definitely go there and have a look. But I also made some mental preparations in case that the two locals were just bragging and that the Red Stone Gorge was not as beautiful as they described.
To our great surprise, the Red Stone Gorge is indeed an extraordinary place and it turns out to be the biggest cliff grottoes in Shaanxi Province. On both sides of the auburn cliffs of the gorge are countless inscriptions and caverns of all sizes. At the bottom, a crystal-clear torrential brook is running rapidly. Standing there quietly, we were immediately intoxicated by the long history, enriched culture and beautiful landscape of China.
