Whether Yelang Ancient Town is a karst landform or not, the fundamental conditions for the formation of karst landforms: The reason why karst landforms are widely distributed in southwest my country is that the main body of their development is here.

A large number of carbonate rocks, sulfate rocks and halide salt rocks have formed various peculiar caves on the surface and underground under the continuous dissolution of flowing water.

Karst landscape.

From the perspective of solubility, there are halogenated salt rocks, sulfate rocks, and carbonate rocks; because there are many types of carbonate rocks, the solubility of each type of rock depends on the amount of insoluble impurities, such as limestone, dolomite, marl, and limestone.

From the analysis of rock structure, the larger the crystal grains of crystalline rocks, the smaller the solubility; equigranular rocks have smaller solubility than unequal granular rocks.

Yelang Ancient Town is located in the northeastern part of the Yunnan-Guizhou Plateau, about 550 meters above sea level.

Since the establishment of Yelang County in the Tang Dynasty, the name of Yelang has never been changed in 1358 years. It is the only town named Yelang in China today.

Yelangba was an important transportation road in the Tang and Song Dynasties.

After Yelang County was evacuated in the second year of Xuanhe (1120) of the Northern Song Dynasty, it was still an important transportation thoroughfare.

In the early Ming Dynasty, after the post road was changed out of Songkan, it became a rural market town.

The streets are in the shape of a folding ruler, and the streets are in the shape of bluestone fish ridges.

The territory has undulating mountains and crisscrossing valleys, which is a mid-mountain hilly, canyon and basin landform.

There are dense rivers and gullies and rich water resources. The Yelang River contains seven streams from the north and south. It is convenient for irrigation and has a warm climate. Yelangba is known as Wulongchang and was once a double-cropping rice cultivation area in the county.

The main food crops are corn, rice, soybeans, and wheat.

The main economic crops are rape, flue-cured tobacco, and peanuts; the forest side products include citrus, wood, bamboo shoots, gastrodia elata, raw lacquer, tung oil, tea, palm flakes, etc.; the mineral resources include coal, iron, and limestone.

7 villages have access to electricity; 4 villages have access to roads, with a mileage of about 12 kilometers.

There are 3 coal plants with an output value of more than 100,000 yuan.

Yelang Ancient Town is located in the northeastern part of the Yunnan-Guizhou Plateau, in the middle of the vast Dalou Mountains that stretches for thousands of miles, like a huge jadeite, leaning against the mountains of northern Guizhou.

Yelangba is an open valley in the mountains, about 550 meters above sea level, surrounded by hundreds of fields. The Yelang River, which originates from Licunba in Xishui County, has gurgling, crystal-clear water, with bamboo and willows supporting the banks. It is in the west corner of the valley.

Near the Yelang River platform is the ruins of the ancient Yelang City.

The central street of Yelang Town is in the shape of a ruler, all in the shape of a wide-eaves corridor (living hall). The wooden street buildings on the first floor and one bottom are arranged opposite each other. The bluestone streets with a width of more than ten feet are in the shape of a fish spine.

Yelangba is the ruins of an ancient county town. It is located near Bashu and was developed earlier.

Since the establishment of Yelang County in the Tang Dynasty, the name of Yelang has never been changed in 1358 years. It is the only town named Yelang in China today.

Although Yelang Kingdom was an independent kingdom at that time, its land area was very small, equivalent to a county in the Han Dynasty. Moreover, it produced very few things and few animals.

However, the king of Yelang Kingdom was very proud and arrogant.

He believed that the country he ruled was so large and wealthy that perhaps no country in the world could rival it.

Once, the Han Dynasty sent an envoy to visit the Yelang Kingdom, but the king did not know how high the sky was and asked arrogantly: "Compared with the Han Dynasty and the Yelang Kingdom, which country do you think is greater?"

When asked so suddenly, everyone was stunned. They didn't know how to answer for a while, but they all felt it was funny in their hearts.

This is the legend and origin of the idiom "Yelang is arrogant".

"Yelang is arrogant" is used to describe the superficial conceited or arrogant behavior of pride and ignorance.

"Yelang is arrogant" is an idiom with the highest recognition rate in the Chinese circle.

Chinese reference books interpret it as an allegory for those who are arrogant. Many people know that there once was a Yelang Kingdom in the ancient southwest through this idiom.

People in the world have been familiar with Yelang for a long time because of the idiom "Yelang is arrogant", and mistakenly think that Yelang is a small country.

In fact, as recorded in "Historical Records: Biographies of Southwest Yi": "There are many kings of Southwest Yi, and Yelang is the largest." In the sixth year of Emperor Wu of the Han Dynasty, Tang Meng, the general of the southern expedition, wrote to Emperor Wu that Yelang had "one hundred thousand elite soldiers."

"Hanshu: Biography of Southwest Yi" says that it threatens "twenty-two nearby cities" and has many trade exchanges with neighboring countries.

Since the Yelang Kingdom had hundreds of thousands of elite soldiers, the economy was relatively developed among the southwestern barbarians, and it had a vast territory and a large population, even the powerful Western Han Dynasty did not dare to underestimate it. Therefore, Emperor Wu awarded the seal ribbon to the leader of the Yelang Kingdom.

"Historical Records" records: "There are hundreds of barbarian kings in the southwest, Du Yelang and Dian received the king's seal" and were named kings.

In 32 BC, after Emperor Cheng of the Han Dynasty came to the throne, Yelang's power became increasingly powerful, and the Han Dynasty was uneasy, so he sent heavy troops to conquer it. On June 23, 27 BC, the local government of Yelang was eliminated.

A brief introduction to the mysterious ancient Yelang country. Where is the ancient Yelang country today?

Or called Nanyi.

The area is roughly Guizhou, western Hunan, and northern Guangxi.

From the Qin Dynasty to the early Han Dynasty, Yelang had entered a settled agricultural society.

The land is rainy, there are few livestock, and there are no sericulture. It has economic ties with Ba, Shu, Chu, and South Vietnam.

Local products such as wolfberry sauce from Shu are often transported to South Vietnam via Yelang.

The history of Yelang Kingdom roughly started from the Warring States Period to the Heping Period of the Western Han Dynasty, which lasted about 300 years.

Afterwards, Gu Yelang Kingdom mysteriously disappeared.

This ancient civilization has left a fog in historical records.

The archaeological excavation of the "Southwestern Yi" tombs in Hezhang Cola has revealed a glorious corner of the mysterious Yelang culture.

Chinese culture is a complex of multiculturalism.
