Taihang Mountains.

The most beautiful section of Taihang Mountain is reserved for South Taihang. The red stone walls stand thousands of feet high, spreading out layer by layer like an axe, a chisel, or a knife. They are witnesses of the deposition of the earth over hundreds of millions of years. Youlong Bay is as graceful as a wandering dragon, and cotinus trees are red all over the mountains and fields. What a surprise to encounter such scenery this season. Unfortunately, we encountered heavy fog. If it's sunny, the water in Youlong Bay is even more beautiful.
