[Check in] On the weekend, I took Meimei to Zhanggongdong! Yixing is really far enough! The beauty entered the cave for the first time. I was yearning, scared, and felt like a scene where a ghost blows a light. This is dark, wet and cold full of mystery! There is also a flowing underground river! I dare not walk alone in the narrow, but there will be opportunities to go to more beautiful caves in the future!
