"Wulong Tiankeng and Difen | Mysterious Underground Adventure in the Fog City."

| Mysterious Underground Adventure in the Fog City." 😎 Guys! You must visit Wulong Tiankeng and Difen Scenic Area in the Fog City! It's like a mysterious alien world here. 🧐 The Tiankeng is magnificent and spectacular, with a huge pit like the open mouth of the earth, steep walls, and green plants still growing tenaciously, full of vitality! The Difen is deep and narrow, with gurgling streams and mist, and every step is full of surprises. I love it! 💕
