Walking out of the fairy Palace, along the underground river, we came into another part of the world. Here you will see a natural hole called Tiankeng. Tiankeng is 110 meters deep and 43 meters in diameter. The wall of Tiankeng is upright. There are six layers of Tiankeng wall. There are Canyon waterfalls in the cave. It is a rare spectacle in China.
Here we can also see the natural stone bridges. When the weather is good, the water mist rises and the rainbow can be seen. Therefore, these bridges are also called the overlapping rainbow bridges.Under the stone bridge, the flow is swift and across the dark river, forming another wonder.
Along the river bed, there will be a whirlpool, and a loophole is in the direction of the current.
Walking along the underground river, the roar of running water will be heard all the way inside the cave, and the roar will be tremendous. When you see the water vapor, you will come to another wonder, the double waterfalls of male and female. The waterfall is 30 meters high, 10 meters deep and the maximum flow of water is 320 cubic meters per second. The roar is so strong that you will hear it far away. It is also the only spectacle in the cave in China.
The travelers stand in line and take photos in front of the twin waterfalls quickly. I also took a photo quickly .
Watching Jiuxiang Karst Cave and Waterfalls is one of my most shocking places. Unexpectedly, the underground river in the cave has formed such great waterfalls made people unforgettable . I think it is also a great wonder in the world.
从神女宫出来，沿着地下暗河，进入到另一片天地，会看到一个天然形成的洞，叫天坑。天坑深度110米， 直径43米，坑壁直立，天坑壁出现六层，洞内有峡谷瀑布，为国内罕见奇观。
在这里还会看到天生石桥，天气好时，水雾腾起，能看到彩虹，因此这些桥又被称作叠虹桥。
叠虹桥下水流湍急，横跨于暗河之上，形成又一道奇观。
沿着暗河河床，会有漩涡坑，水流方向有缺口，河水打成旋涡，奔腾而去。
沿着地下暗河走，洞内老远就会听到流水的轰鸣声，前行，轰鸣声响天震地，看到水汽的时候，就来到了又一奇观， 雌雄双瀑。瀑布高达30米，瀑布下潭深10几米，瀑布最大水流量每秒320立方米，轰鸣声震耳欲聋，是国内溶洞内仅有的奇观。
人们在双瀑前达成默契， 因为要照相的人很多，因此排队，轮到了，快速的跑上前去，拍个照下来，空气中漂浮着水雾，感觉浑身湿漉漉的。
观看九乡溶洞，看雌雄双瀑，这个景点是令我最为震撼的地方，没想到溶洞内暗河竟然形成如此壮观的瀑布奇观，我想这在世界上也是令人震撼的吧！
