Planning is required to do everything, and there are two types of planning. One kind of planning is called rational planning, and one kind of planning is called careful planning.

The difference between reasonable planning and careful planning is not a star and a half, which is also the key to success or failure.

Some people always think that they are very creative, some people always think that they are very talented, there are many people with ideas, and there are many talented people. But there are not many people who have ideas and talents, who are reasonable and meticulous but even less planned.

If you look at life as a play, then the first half of the stage is just the opening ceremony, and the real wonderful drama has not yet begun.

When she became the leading actor and director of this scene, Mei Xiaohan gradually found that it was not so easy to perform this scene well, and it was even more difficult to achieve the effect she expected.

He has to be around everyone and socialize with everyone, not necessarily everyone's approval, but at least to satisfy himself.

However, there are no ifs in life, and when time is gone, no one will regret it. What should be grasped, what cannot be grasped, what has passed away, can only become a memory in the end.

Now it is time for another critical period, that is, the development of the city, although the city is now firmly controlled by himself, but he feels that it is not yet secure, and there is a risk of losing it at any time.

Just like the development of history, it is never smooth sailing, and sometimes there are even regressions. This phenomenon is inevitable to occur and emerge.

Only by understanding history can we know how to avoid certain things from happening.

History will always remember that that day, that day, it was the day in 1279, and the words "there is no China after Yashan" came out on that day.

A.D. 1279, this year is the second year of Xiangxing in the Southern Song Dynasty, and this year is also the sixteenth year of Yuan to Yuan.

During China's thousands of years of history, the Song Dynasty was a period of rapid development in agriculture, handicrafts, commerce, foreign trade, science and technology, and cultural undertakings.

The achievements in astronomy, mathematics, medicine, agronomy, architecture and other fields not only surpassed their predecessors, but also were far ahead of the world at that time.

For more than 300 years, the Northern and Southern Song Dynasty emphasized literature and suppressed military force, and was repeatedly humiliated by foreign enemies militarily, and was often called "weak Song Dynasty".

However, looking at the Song Dynasty comprehensively, it has reached the peak of China's feudal society in many aspects such as economy, culture, science and technology, agriculture, industry and commerce, handicrafts, etc., and its achievements have surpassed those of the previous Sui and Tang dynasties and the subsequent Ming and Qing dynasties, and it is the only dynasty in Chinese history that has not suppressed industry and commerce.

The Song Dynasty vigorously developed foreign trade, and although it continued to pay tribute, the treasury was still abundant.

When the northern nomads began to occupy northern China, they resorted to genocidal means. If you look through history, you can find that every city has a record of slaughter.

The Mongol massacres caused a significant depopulation in northern China, where there were more than 45 million registered people, compared to less than 7 million after the massacres in various places.

After the invasion of the Mongol Yuan, the Han civilization never regained its strength, and the development of civil society, the development of a new commercial economy, and the innovation of science and technology all came to naught, and China once again shook its advantage of leading the world.

Genghis Khan was one of the greatest military strategists of all time, and his Mongol legions were the most powerful conquerors on earth.

Genghis Khan's horsewhip pointed out, and the iron hooves everywhere they went. But Genghis Khan always looked down on the Han people who could not ride and shoot and were weak, and he never took the Southern Song Dynasty seriously.

When he first started his army, Genghis Khan always regarded the Jin people as his strongest opponent, but the Jin soldiers disappointed him, and the 100 years of arrogant life in the Central Plains had long since worn out the Jurchens' bravery.

After Genghis Khan occupied the central capital of the Jin Dynasty, "the Jin Dynasty had five national capitals, which were called Shangjing, Tokyo, Xijing, Beijing and Zhongdu. ”

Shangjing is the place where Wanyan Agu beat his teacher, in Huining Prefecture, located in the south of Acheng County, Heilongjiang Province. Later, the Jin Dynasty moved south, and Shangjing became a symbolic capital, which was related to sacrifices. Every year, the emperor has to go to Beijing when he hunts in the north and deal with the corresponding government affairs in Shangjing.

Tokyo is Liaoyang Prefecture, which is now Liaoyang, and the Liao Dynasty called it Nanjing. Kim Taejong Tenkai changed its name to Tokyo in ten years. Its purpose is to administer the Korean region.

Xijing is the current Datong, which was called Datong at that time. The Liao State took Datong as the western capital. In the fifth year of Jin Dading, he built a palace there and built the Jin Taizu Temple. Its camp is quite similar to that of Zhongdu. In the management body, there are the Left-behind Division, the Transit Division and the Zhongdu Xijing Road Criminal Division, which are the most valued among the four accompanying capitals.

The Beijing of the Jin Dynasty was located in what is now Ningcheng County, Inner Mongolia. During the Liao Dynasty, Dading Mansion was used as Zhongjing, and during the Jin Dynasty, it was changed to Beijing.

Zhongdu was the political center of the Jin Dynasty, and Zhongdu was originally known as Yanjing, and it was also known as Nanjing in the Liao period. King Hailing of the Jin Dynasty thought that Yan was the name of the country, and it was not suitable for the name of Jingshi, so he changed his name to Zhongdu. It is the southernmost of the 5 capitals. As you can see from the difference between the names of the other capitals, the others can only be called Kyoto, and only it is called the capital. ”

After Genghis Khan occupied the central capital of the Jin Dynasty, the Jin people had no choice but to pay tribute to him.

In the first western expedition, Genghis Khan did not encounter an opponent, and only encountered decent resistance from the main force of Western Xia in the Battle of Lingzhou during the conquest of Western Xia.

History is often a joke, and by the time of Genghis Khan's death, he never dreamed that his most despised Han Chinese would be the strongest opponents and the most difficult bones in the history of Mongol conquest.

After Genghis Khan's death, his son, Ögedei Khan, effortlessly destroyed Jin in 1234, according to his strategic plan before his death.

In 1241, the Mongol expeditionary force crossed the Danube River in Budapest, annihilating 100,000 European troops and completely destroying the city of Budapest.

In the same year, the Mongol Great Khan Ogedei died of illness, and the Mongol expeditionary force returned to China to participate in the struggle for the Khan's throne, and did not take a step to the west.

At the same time, he also divided his troops into two ways to attack the Southern Song Dynasty, the east road to attack Xiangfan, Jianghuai, and the west road to attack Sichuan.

However, the Mongol army encountered stubborn resistance from the Song army, and it was not until the following year that the Western and Eastern Route armies captured the two strategic points of Yangpingguan and Xiangyang, respectively.

The Mongol army began to assemble along the Yangtze River in Hubei, preparing to cross the Yangtze River, and the Southern Song Dynasty sent the general Meng Heng to the rescue.

Meng Heng soon broke through 24 Mongolian villages in a row, achieved a great victory in Jiangling, prevented the Mongol army from crossing south, and broke the myth of the invincibility of the Mongol army in one fell swoop.

In the following years, the Song army, led by Meng Hui, waged a fierce tug-of-war with the Mongol army, and the two sides were indistinguishable.

In 1239, the general Du Gao defeated the main force of the Eastern Mongolian Route Army in Luzhou, and the Eastern Mongolian Route Army suffered heavy casualties and was forced to retreat. Meng Heng turned to a counteroffensive, defeated the Mongol army in succession, recovered Xiangfan Prefectures and Xinyang, and basically lifted the threat of the Mongol army to the Southern Song Dynasty on the eastern route.

At the beginning of 1240, the brave Meng Hui defeated the Mongol army on the Western Road, won a great victory in Dayazhai, and recovered Kuizhou. The Mongol army besieging the Southern Song Dynasty on both sides suffered a complete setback.

In 1241, the Mongol Great Khan Ogedei fell ill and died, and the Mongol army on the Western Route withdrew from Sichuan. Thus, the six-year-long Mongol-Song War ended in the defeat of the Mongols, which was also the first major setback in the history of Mongol conquest.

In 1241, after the death of the Mongol Great Khan Ogedei, his son Guiyou succeeded to the throne, but died two years later.

During this period, the Mongol army invaded Sichuan, but was defeated by the Southern Song general Yu Jie.
