Between the majestic and solemn Cangshan Mountain and the quiet and beautiful Erhai Lake, there is a narrow and long dam, about a hundred miles long and less than ten miles wide. There are only two extremely narrow exits between the north and south valleys, which are called Longshou. Pass and Longwei Pass, this natural and dangerous dam, which is easy to defend and difficult to attack, is Dali.This is an endlessly fertile land. As the meeting point of East Asia, South Asia and the Qinghai-Tibet Plateau, for thousands of years, passionate legends and stories have been staged, and splendid culture and history have been written...

Li Bai, a great poet of the Tang Dynasty in China, wrote a poem "The Road to Shu is Difficult", in which he lamented three times that "the road to Shu is more difficult than going to the blue sky", and he said that the road to Shu is as difficult as going to the blue sky.In fact, in the south of Sichuan, there is another place called "Dian" in ancient times. The terrain is more intricate than Sichuan, and it is more difficult to reach.Precisely because the road to Dian is far more steep than the road to Shu, Yunnan has long been isolated from the Central Plains and is considered a barren land where plagues are prevalent.In fact, it is like spring all the year round, with beautiful scenery, and it is definitely not the smoky place that outsiders imagined.

The strangest scenery in Yunnan is that of western Yunnan - high mountains, dense forests, and alternate ridges and valleys. Although more than 90% of the land is mountainous, there are many basins commonly known as "Bazi" scattered among the lush mountains. There are plateau lakes such as Cibi Lake, West Lake, and Jianhu Lake. They are really surrounded by mountains and water, with sky and cloud shadows, which is a beautiful picture. In western Yunnan, there is a famous Cangshan mountain range, also known as Diancang Mountain, which means "Mountain of White Head".There is a large lake on the east side of Cangshan Mountain, called Erhai Lake, which is also running from north to south. It is shaped like an ear, no more than a hundred miles long, and about ten miles wide.To the east of the Erhai Lake, there is another mountain range rising from the water. The strange peaks and ravines and jagged rocks form a barrier, so that someone carved a poem on the stone wall of Dahe Lake, "this water can serve as a hundred thousand soldiers".

Just between the majestic and solemn Cangshan Mountain and the quiet and beautiful Erhai Lake, there is a long and narrow dam - about a hundred miles long and less than ten miles wide, leaning against Cangshan Mountain in the west and Erhai Lake in the east. Bazi is surrounded by mountains on all sides, and there are only two extremely narrow exits between the north and south valleys-named Longshouguan and Longweiguan respectively.This naturally dangerous dam, which is easy to defend and difficult to attack, is Dali.This is a fertile land with endless life. As the intersection of East Asia, South Asia and the Qinghai-Tibet Plateau, for thousands of years, passionate legends and stories have been staged, and a splendid culture and history have been written.

During the Han Dynasty, Liu Che, Emperor Wu of the Han Dynasty, sent Zhang Qian as an envoy to the Western Regions.Zhang Qian saw cloth and bamboo sticks from China's Shu real estate for sale in the Daxia Kingdom, and only then did he know that he could go directly to Shendu from Sichuan via Dali.After Liu Che got the report, he sent envoys to explore this legendary hidden and dangerous Southwest Silk Road many times, but he never succeeded.In 120 BC, Liu Che ordered people to excavate a large lake of more than forty miles in Chang'an, the capital, and named it "Kunming Lake", and built buildings and boats to practice water warfare in it. The allusion of "Han learning building and boat".In 109 BC, Liu Che sent General Guo Chang to enter Yunnan by force, and finally succeeded in setting up Yeyu County in the Erhai Lake area, thus bringing Dali into China's territory.

During the Three Kingdoms period, Zhuge Liang, the prime minister of the Shu Kingdom, captured seven times and surrendered Meng Huo, the surname of Nanzhong. The southern lands began to bloom.Since then, the Wuhou Temple has been established in Yunnan, and statues of Zhuge Liang and Huang are built inside to show respect. In 320 AD, the Cuan family entered Yunnan, and Cuan Chen became king in Kunchuan (now Qujing, Yunnan), and the Cuan family ruled for four hundred years. In the Tang Dynasty, several tribes such as Liuzhao and Xierhe Man were formed in the Erhai area. The Liuzhao were all Wuman tribes. Among them, Mengshezhao lived in the south of the Liuzhao, also known as "Nanzhao".At that time, Tubo became stronger and stronger. Since Zanpu Songtsen Gampo unified Tibet, he not only dominated the snow-covered plateau, but also expanded eastward, which seriously threatened the safety of the southwest and northwest borders of the Tang Dynasty. Between Tubo, it will inevitably become the focus of interests of both parties.In 707 A.D., Tang Zhongzong Li Xian sent Tang Jiuzheng as an envoy to attack Tubo from the southwest, demolished the chain bridges on Yangshui and Bishui, and cut off the communication between Tubo and Liuzhao.Tang Jiuzheng used the iron bridge material cast iron pillars to record his merits on the spot, which is the allusion of "Tang Biao Iron Columns".

In order to further contain Tubo, Tang Xuanzong Li Longji secretly supported Nanzhao to annex the other five imperial edicts, established Nanzhao Kingdom, and unified Yunnan.After Nanzhao became powerful, the relationship with the Tang Dynasty was not harmonious.There were also many internal contradictions in Nanzhao. In 902 AD, Zheng Maisi, a human rights minister of the Han Dynasty, seized the throne and changed the name of the country to Dachanghe.Twenty-seven years later, another power minister, Zhao Shanzheng, destroyed the Dachanghe Kingdom and established the Datian Xingguo.The following year, Dongchuan Jiedu envoy Yang Qianzhen seized the throne and changed the country's name to Dayining.In 937 A.D., Duan Siping, an aristocrat of the Bai nationality, destroyed Dayining and established the Kingdom of Dali with the capital Yangjubaa City.

At the same time, the Central Plains was also undergoing a dynasty change. Zhao Kuangyin launched the Chenqiao Mutiny to establish the Song Dynasty, and immediately launched a series of wars to unify China.In 965 A.D., Song general Wang Quanbin invaded Sichuan, annihilated Hou Shu, and intended to continue the southward attack on Dali.However, Zhao Kuangyin pointed to the Dadu River on the map with his jade ax in view of the more serious problems in the north, and said, "I don't own anything else." This is the source of "Song Hui Yu Axe".Several emperors in Dali admired the culture of the Central Plains and actively established friendship with the Song Dynasty. However, the Song Dynasty was always on guard in view of the lessons of Nanzhao's rebellion against the Tang Dynasty in the past.Fortunately, the whole country of Dali believed in Buddhism, and the previous emperors had no intention of aggression and expansion. Therefore, although the relationship between the two sides did not make any substantial progress, it did not deteriorate to the point of fighting each other.

At the end of the Southern Song Dynasty, in order to destroy the Southern Song Dynasty and worry about the power of the Central Plains, Mongolia decided to conquer the southwestern tribes first, and then formed a strategy of attacking the Southern Song Dynasty from the north to the south.In 1253 AD, Mongolian Khan Mengge sent his younger brother Kublai Khan to lead an army of 100,000 to attack Yunnan.Kublai Khan led his army across mountains and ridges, crossing rivers and crossing rivers. When they reached the west bank of the Jinsha River, he ordered his soldiers to kill cattle and sheep, plug their anuses, and blow them into leather pouches to cross the river. This is the famous "Yuan Kua leather pouch".After crossing the river, the Mongolian army quickly went south, defeated the defenders of Dali, killed Gao Taixiang, the prime minister, and captured Duan Xingzhi, the emperor of Dali.

Sensing the popularity of the Duan clan, Mongolian Khan Mengge implemented a soft policy and bestowed Duan Xingzhi with a golden talisman, allowing him to go back and continue to rule Yunnan.After the founding of the Yuan Dynasty, in order to appease the people, Kublai Khan set up the "Military and Civilian General Administration Office on Dali Road" in Dali, with the Duan family as the general manager. The king of Yunnan, went to Yangjubaa to guard.Soon, Kugechi was poisoned and killed. Kublai Khan felt that the political affairs in Yunnan were complicated, so he sent back Sai Dianchi to establish a province in Yunnan, moved the provincial capital to Shanchan, and renamed it Zhongqing, in order to weaken Duan His strength.Because Yunnan is located at an important border point, the Yuan court also sent another Zongwang to guard it, called "Yunnan King" or "Liangwang"-the Yunnan King has the right to supervise, intervene in provincial affairs, command troops, and command operations; The rank is higher, above the king of Yunnan, as the first-class king, awarded the golden seal animal button, holding heavy troops, supervising, pre-preparing provincial affairs and commanding the use of troops, and is the highest representative of the Mongolian royal family in Yunnan.The jurisdiction of the Duan clan in Dali was compressed from the whole of Yunnan to Dali 1st Road, but in fact the Duan clan still had considerable control over the vast old Duan clan in western Yunnan centered on the Erhai Lake area.From then on, Liangwang, Xingsheng, and Duan's three families took power in Yunnan together and checked each other, starting a power struggle that lasted for a hundred years.

As the saying goes, "Personnel and affairs are metabolized, and the exchanges become the past and the present." Cold comes and summer goes, spring and autumn come, and time is constantly passing by.At the end of the Yuan Dynasty, the world was in chaos, and hordes rose up. The Red Scarf Army of the peasant rebels defeated the main force of the Yuan army one after another, and their strength gradually became stronger.At a critical moment, Tuohuan Tiemuer, the emperor of the Yuan Dynasty, listened to the traitor's slander, and demoted Tuotuo, who was known as a "virtuous minister", to death in Yunnan. The towel army was fighting, and the internal strife continued, attacking each other, and Tuohuan Tiemuer finally fell into a situation of isolation and helplessness, and the emperor ordered him to leave the capital for fifty miles. In 1363 AD, the twenty-three years from the Yuan Dynasty to Zhengzheng, the situation in the Central Plains gradually became clearer. Zhang Shicheng, who was born as a salt merchant, after years of dismal management, and Zhu Yuanzhang and Chen Youliang, who were born in the Red Scarf Army, dominated the southeast area; Ming Yuzhen, who was born in the red scarf, occupied it; Chen Youding and others separated the Fujian-Guangzhou area, but their forces were relatively weak; the Central Plains from Henan to the north of Shandong were still firmly controlled by the Yuan court, and the Yuan general Wang Xuan led heavy troops to station in Shandong. However, Wang Baobao, the most powerful general of the Yuan army, was entrenched in the hinterland of Henan. However, he was headstrong.The generals in Guanzhong of the Yuan Dynasty even elected Li Siqi as the leader of the alliance, and united to deal with Wang Baobao.You come and go, the two sides fight each other with real knives and real guns.The emperor of the Yuan Dynasty issued edicts many times, but they could not stop them. This year, the Lunar Calendar is Kuimao Year, and the flames of war are burning all over the Central Plains. No matter who it is, it is an extremely turbulent year.Even the Yunnan Province, which is located on the border, is under the threat of soldiers. The Great Xia Emperor Ming Yuzhen, who occupies the fertile land of Western Shu, took advantage of the fact that the Yuan court could not look after each other, and personally led an army to attack Yunnan Zhongqing.Seeing Ming Yuzhen's menacing army, Polo, the king of Yuanliang who was in Yunnan, hurriedly mobilized the army to resist. While the land of China is devastated and moaning, the southwest has a unique paradise in Dali, where there is no cold or heat in winter and summer, and there are endless flowers and trees in all seasons.It is the ninth generation that the position of Dali General Manager has been handed down to this day. The name of the general manager is Duan Gong, who is more than thirty years old.The story of this book begins in Dali.
