Bermuda, the pyramids, the Sphinx, the Dead Sea, the Sahara Desert, the mystery of the savages of the dragons... You must not be strangers to these names, but do you know? They share a common feature - 30 degrees north latitude, this mysterious line of the region has many mysterious world wonders. Today, another world puzzle on this line is in front of usthe Huashan Mystery Cave. There are 36 grottoes in the Huashan Caves. Today only the No. 2, No. 24 and No. 35 grottoes are open, and others are still under development. This time we mainly visited the No. 2 and No. 35 grottoes. The No. 2 Grottoes are also called the Ring Creek Grottoes. The grottoes are halfway up the mountain, and the mouth of the cave is opened. After entering the hole, the slope will be extended, the air will be immersed in the air, and the hole will be looked back. It has already been foggy. There are dozens of stone pillars standing upright in the , which form an underground corridor with a length of 80 meters, a width of 15 meters and a depth of 4 meters. In the 2nd cave, a natural autumn color picture is once again amazing. I saw that the whole picture was rendered by the brown autumn leaves: the black jungle, the peaks and the ancient dwellings were dotted in the autumn leaves, and the ancient dwellings could clearly see the architectural style of the Hui. In the vicinity, a small white river passes through the ancient dwellings, which is undoubtedly the Xin'an River at the foot of the foot of the cave.
