Can the "Cave at the Peak" be counted? (*Hee-hee.......)

Hello, I have collected relevant information for you The largest cave in the world is called Han Song Cave, which is located in Quang Binh District, Vietnam. There is a different scenery in the cave. The cave is large, with a length of about 8,855 meters, a width of 198 meters, and a height of 150 meters.

Over time, the caves will expand even further, with some saying it could hold billions of people. There is a cave here, this cave is like a small world, with woods and rivers in it, like a paradise. Separated by a hole are two different worlds.

Have a great trip.

There are many kinds of tourist landscapes in the world, if you talk about the cave, the largest is Han Song Cave in Quang Binh Province, Vietnam, the cave is about 8,855 meters long and 198 meters wide. The regiment is trapped vertically.

In the Vietnamese region, the cave was discovered by a farmer who got lost.

The largest cave in the world is next to Lake Baikal, the cave here is very large, and there is a sound in the bottomless darkness, which is very terrifying, and no one dares to enter it.

The longest cave in China is the Shuanghe Cave in Suiyang County, Guizhou Province.

The Shuanghe karst cave system is a network-like underground river system formed by repeated intermittent neotectonic uplift and continuous downcutting of underground rivers, and the age of the caves is about 2 million to 3 million years old. At present, the length of the cave is 138 kilometers, and it is the "longest cave in China".

France built the Yunnan-Vietnam Railway for the purpose of plundering Yunnan's resources and obtaining huge profits from the colonial economy. At that time, a French pointed out that "after the completion of the Yunnan-Vietnam Railway, not only the commerce of Yunnan Province was controlled by the French, but also Yunnan ** was also in the hands of Paris**." "From 1915 to 1920, the Yunnan section of the French Yunnan-Vietnam Railway Company made an average annual profit of 1 million francs, which increased to an average annual profit of more than 600 million francs from 1912 to 1930.

From 1914 to 1930, the French collected 14.55 million yuan of silver yuan from Yunnan. From 1909 to 1938, France transported 23,424 tons of large tin from the Yunnan-Vietnam Railway. The Yunnan-Vietnam Railway Project, known as the "Heavenly Train", built a hundred years ago, is an amazing feat even today when science and technology are highly developed.

From 1897 to 1903, the French spent seven years surveying the line in a precise and detailed manner, using the most advanced surveys in the world at the time. The 466-kilometer Yunnan section, from Kunming to Hekou, will drop from 91 meters above sea level in 2030, a difference of 22 times. There are 3,628 bridges, culverts and caves on the whole line, including 107 bridges over 20 meters long, 172 caves with a cumulative length of more than 20 kilometers, the longest cave is 657 meters, the longest stone bridge is 70 meters, and the longest steel bridge is 136 meters.

In total, nearly 16,000,000 cubic meters of earthwork were moved by manpower, of which 4,000,000 cubic meters were entirely rocky. In some places, the slope is steep and the bend is sharp, the maximum ramp, the minimum curve radius is 80 meters, and the length of the whole curve is more than half of the total length. 220 kilometers from Kaiyuan to Hekou section, the train takes 10 hours and 30 minutes, and the average speed is only 20 kilometers per hour.

Another casually described the hardships of this railway: "a serpentine railway, a boat-shaped train, a heroic driver, and a passenger who is not afraid of death."
