The scenery of the ancient cave of "Yunnan First Cave" is amazing. The cave is winding and colorful. Sometimes the mountains and rivers are heavy, sometimes the willows are dark and the flowers are bright, and the cave is three kilometers long. The huge landscape painting, underground dark river, and the origin of life are impressive. It feels inconvenient that the ticket gate of the scenic spot is actually in the cave. One or two hundred meters on the surface, the online ticket pick-up point sign is not obvious, and the online ticket purchase should pay attention to the messy landscape planning from the parking lot to the cave entrance. Many road signs are not obvious. I hope to continue to improve!
