Ancient citadel (Tk 1 BC - 5 AD)

The ancient Kingdom of Poland over 2100 years ago was a transit trading post on the Silk Road linking China, Persia, India, Syria, and the Roman Empire. At the same time, it is also one of the most prosperous, largest urban centers in the world. However, around 500 years ago, it mysteriously disappeared in Chinese history in just one night, many nomadic people also disappeared . Where did they go? How many years this is still a riddle.

Based on historical records, Lau Lan is a large city. In the city of people living crowded, outside the field of the field straight stork. Of the 36 countries in the Western Region (Xinjiang's economic and cultural Xinjiang were most developed. During the Mesopotamian period, the relationship between the Lan and the interior was always very close, but after the Wei Jin Nan period. Dynasty, Lan Lan gradually cut off relations with the inland, then quietly disappeared in Chinese history.In the Tang Dynasty, although the Silk Road was still smooth, people did not know where Lan was. Some contemporary writers and poets refer to Lau Lan, but they are just a substitute for "nouns" , and they do not know the whereabouts of this ancient city.

So where did the ancient castle of Lan Lan disappear to?

Scientific researchers offer many different explanations. Some people believe that the cause may be La Bo Lake dried up, the change of natural circumstances, the river changes the stream . There are also people who say, upstream of the Khuc Tuoc river unreasonable. Someone pointed out that, due to the changing silk line, or another invasion. What is the real cause of Lan Lan disappearing?

In the spring of 1900, Swedish explorer Seven Herdin, while exploring the West Lake of La Bo, instructed Duy Ngo Ardic to return to the survey camp to pick up a hoe when he encountered a storm and lost his way. After that incident, this brave guide not only returned to the survey camp, obtained the hoe, but also discovered a large Buddha tower and ruins.

The intricate sculpted trees here are half buried in sand, there are also ancient coins. In 1903, Seven Herdin officially entered this ancient citadel. He was dumbfounded at the sight that caught his eye. In a 300m-long wall, the beams are scattered under the sunlight and hot dry sand. Based on the design style of the architecture, it can be judged that this place is a government agency, the other place is the people, there is another temple . There is a tall Buddha tower in the middle of the ancient city. Seven Herdin excavated this ancient city, collecting many valuable artifacts.

Wooden cards and letters document the cultivation and transportation of local food, numerous elaborate documents and coins dating to the Chinese dynasties. These artifacts reflect high economic exchanges between this region and the inland. While excavating, this brave explorer unknowingly discovered a note stating the word 'Lan Lan'. Since then, the ancient castle of Lan Lan disappeared for more than 1000 years has appeared. After returning home, Herdin declared, I discovered the famous Castle of Lan in Chinese history. This discovery has shocked the world.

Castle of the Castle has been found, but people raise a new question: Why did Castle Castle suddenly disappear? As for the cause of the disappearance, the scientists conducted many exploration, giving a lot of speculation as well as different judgments.

It is said that around Lan Lan, there are many powerful ethnic groups h. These ethnic groups have used cavalry to break through the peaceful country, plundering and destroying ancient city dwellers. As a result, this ancient city became deserted. In fact, this explanation cannot find historical evidence.

Some people believe that the destruction of the ancient castle of Lan Lan is due to climate change. The climate here is extremely dry, without rain for many years. This climate is an ideal condition for the preservation of antiques. The bodies of thousands buried at the bottom still do not rot, becoming 'mummies'. They speculate that, over the past 2000 years, the climate in Central Asia was developing in an increasingly dry direction. Lau Lan flourished, the climate was quite mild and humid, suitable for growing plants. Later, the climate was dry, more sandy wind, the plants had no seed for many years. Agriculture cannot stand. In an extremely harsh situation and with no way to live, people were forced to relocate.

The above two explanations have some arguments, but are not recognized by academics, because they do not provide specific evidence to prove those claims.

Now academics have a new explanation - 'water short theory' . They believe that this hypothesis can explain exactly the loss of Lan Lan, Lan Lan which is located in the eastern basin of Ly Moc Tower - an extremely dry place. The ancient castle of Lan Lan is located in the lower part of Thap Ly Moc river, next to La Bo lake, which can irrigate crops and develop agricultural production. Later, Thac Ly Moc changed the stream, La Bo lake lost the water source and became a dry place. Lau Lan has since lost its source of livelihood. Residents had to leave this place. The Citadel is gradually buried by the sand. Field surveys outside the citadel can prove this hypothesis. Archaeologists have found ancient river ruins near Lan Lan. Luo Bo history has indeed changed many times.

Judging from the persuasive nature of the hypothesis, this explanation is more likely to fit the truth. Unfortunately, this theory is not found in history books! As a rule, water depletion is a gradual, long-term process of change. If this fact were to occur, the history books must of course be recorded. We believe that scientists will find more accurate answers soon.
