There are three layers of Shanjuan Cave, which are connected by layers. They are divided into upper, middle, lower and four water holes. The holes are connected like a stone sculpture building. In particular, "there is a river in the cave, the river can pass the boat; the boat is in the water, and the hand is supported on the hole." It has always been known as the "Han Cave" in Belgium and the "Lyon Cave" in France. The first thing we walked in was the middle hole, which is also the entrance to the good roll hole. There is a huge stalactite in Zhongdongkou, which is more than 7 meters high. It is called "Zhuzhufeng", also known as "Xiasu Mishan". The first time I saw the surprise of the cave, I lamented the wonders of nature. Don't look at this little stone, it is more than 30,000 years old. Grotesque rocks, colorful lights. The eyes don't know what to look at first. The only way to look at it is to look at the hole. The upper hole is also called the "cloudy field." Because of the temperature and moisture, the hole in the hole is cloudy and foggy. The characteristics of the upper hole are warm in winter and cool in summer, and the seasons are like spring. The temperature is kept at 23 degrees Celsius throughout the year. There is only a narrow corridor in the lower hole, and the flowing water seems to have come to another world. The lower hole is also called "one day." And a waterfall on the stone cliff completely led us into a different world, looking up at this sky, I think the word "Dong Tian" is designed for the good hole.
