Fan Yu finally agreed not to follow him again, but at this time, he ran over to Xin Qiji, stretched out his head and whispered in his ear: "I am going to kill the dog emperor of the Jin Kingdom sooner or later, you have to keep an eye on me, and you must pay attention to how you can kill him." ”

At this time, he saw Fan Yu's goose egg face, big eyes, curved eyebrows, skin like condensed fat, eyes like autumn water, light-colored Luo skirt with silver silk edges, aqua blue gauze with a man's waist, and a long skirt with violet color painted hibiscus trailing the waist and sleeves. With a slight smile, a pair of young and ignorant spirit beads, smooth as pearls, and their eyes were as clear as water. I was blowing like an orchid in my ears just now, and I was so ashamed. Originally, after listening to the words of the little senior sister, I had already taken it to heart, and I would have done it, but I forgot to answer in a panic.

At this time, Fan Jiu'er looked at Ruyu and stayed obediently, and ran over with a smile and said, "My sister looks so handsome, she doesn't look like a princess." Ruyu prepared for several days, but finally couldn't go, she was angry and had no place to vent, so she turned her head and said to her mother: "If I don't go, it's okay, I have to ask my brother to accompany me at home." Su Lan stroked her palms and laughed: "This Xiang is the best, I will help you keep your brother." Fan Jiu'er saw that it was not good, and chased after him.

The group rode fast horses and walked quickly, crossed the vortex river, and headed north to Shangqiu. King Yun disguised himself as riding on a horse, his fair face had become sallow at some point, his nose was flat and red, and he looked like a clown, but his body was straight, and he did not lose his heroism.

Jingkang's Difficulty", the Central Plains was occupied by the Jin people. Xin Zan was burdened by his family's finances and could not get out of the south, so he had no choice but to live in the area occupied by the Jin army with his family. Although Xin Zan served as a doctor in the Jin Dynasty and knew Kaifeng Mansion, he did not forget his family and country, and whenever he had leisure, he took Xin Qijian to "climb high and look far, pointing to the mountains and rivers", hoping to seize the opportunity to expose the rod and oppose Jin. During the years of Jin Tian and others, Xin Zan also twice ordered Xin Qijian to go to Yanjing, the capital of Jindu, to inspect the terrain and collect intelligence in the name of taking the exam. Xin Qiji finally waited for the opportunity to go to the battlefield against Jin as he wished, and when he got in touch with the Southern Song Dynasty, his grandfather Xin Zan had died.

However, during the period when Xin Zan got along with Qi Ji, he did not forget to guide him to learn the geography and history of mountains and rivers, which is something that everyone knows.

Li Bao was very moved when he saw that Xin Zan was about to teach the geography and history of abandoned mountains and rivers again, and couldn't help but say: "Mountains and rivers geography, everywhere you go, you don't forget to point out the rivers and mountains, and the old man has started again." ”

Xin Zan said with a smile: "Huaiying and abandoning illness articles have been carefully taught by Mr. Liu, martial arts have been instructed by Yantang, and military books and war strategies have been passed on by King Yun." I am my grandfather who abandoned my illness, and I happened to teach some of them at the right time today, and my intentions should not be too far from my uncle's ancestors. ”

King Yun said with a smile: "Although he is your own grandson, he is my master's disciple grandson." When it comes to teaching, I am more of a bearer than your own grandfather, and I am naturally not an outsider. The two of us will show our strengths and teach each other. ”

Xin Zan said again: "The prince is much more knowledgeable than me, and you should come." Although I was also a great Song Jinshi back then, the prince was the champion at that time. ”

Zhao Kai, like his father Song Huizong, has been smart and clever since he was a child, with extraordinary literary talents, and is proficient in piano, chess, calligraphy and painting, and is good at painting flowers and birds, so he is deeply favored by Song Huizong.

In the eighth year of Zhenghe, Zhao Kai secretly participated in the imperial examination that year, and won the first place in the examination, Song Huizong was very happy when he learned about it, but he was afraid of being gossiped by the world, after all, it was an unprecedented thing for the prince to win the championship, so Song Huizong named Wang Ang, who was the second in the examination, as the champion, but in fact the champion was still Zhao Kai.

In this way, Zhao Kai became the highest champion in history.

But King Yun shook his head lightly and said: "This is the Central Plains, which has been the foundation of China since ancient times, but now it has fallen. I am a member of the Great Song Dynasty, and I don't have the confidence to talk about this again, so please ask your old brother to talk about it. ”

Xin Zan listened to King Yun's frankness, and his heart was moved, so he said: "The Central Plains has fallen, and the courtiers are even more panicked, but fortunately, we all have the heart to plan again in the future." Today, I will tell you the stories of the battlefields in various places, and if there is anything inappropriate, the prince will advise you again. ”

King Yun smiled and said: "I don't dare to advise, but I may have feelings, I can't help but send it." ”

So Xin Zan said to Huaiying and Qiji: "The Central Plains, also known as Huaxia, Zhongtu, and Zhongzhou, refers to the middle and lower reaches of the Yellow River centered on Heluo.

Zhongyuan means "the wilderness in the world", which is the birthplace of Chinese civilization, the cradle of the Chinese nation, and is regarded as the center of the world. With the great integration of the Chinese nation and the expansion of the Central Plains civilization, the Central Plains region has gradually spread outward, expanding the exchanges between the Han nationality and various ethnic groups with the Central Plains culture as the core, and the Central Plains culture occupies a core position in the process of pluralistic integration of the origin of Chinese civilization. The culturally advanced Chinese nation is called China because it is different from the four yi.

"The Central Plains region is the largest number of dynasties in China, the longest history of building the capital, the largest number of ancient capitals, since the Xia Dynasty, there have been more than 20 dynasties such as Shang, Zhou, Han, Wei, Jin, Sui, Tang, etc., more than 300 emperors set the capital or moved the capital here, the Central Plains has long been China's political, economic, cultural and transportation center, since ancient times there is a saying that "those who get the Central Plains get the world", and the Central Plains can stand the world. ”

Xin Zan sighed here, and then said: "This is the scene before the Jurchens entered the Central Plains, and now the Song Dynasty is only south of the Huai River and the Qinling Mountains.

"Yanshan is the barrier of the north of the Central Plains, and it has been a battleground for soldiers since ancient times. During the Warring States period, Yan Zhao once set up a long wall here to compete with the Xiongnu, and connected it to Qin when it was called, which is the so-called Great Wall. Before the Central Plains was lost in Youzhou, it was at risk. However, since the Later Jin Shi Jingjiao ceded the sixteen states of Yanyun to the Khitan, the barriers were lost and the door was wide open, so it became a personal pain.

"In fact, during the Zhou period, the vassal states set up their own fences and built cities on the border with the enemy, and the Qin period was more vigorously connected and repaired. Emperor Wu of the Han Dynasty fought more with the Xiongnu, and chased it to Mobei, in addition to repairing the Great Wall built by Qin Mengtian, and built the Great Wall from Dawan Ershi City in the west and the Great Wall on the north bank of the Yalu River in Mobei in the east, refusing Hu to be extremely far away. On the contrary, in modern times, the territory of the Han people has been retreating from the north to the south.

"The place outside the eastern head of Yanshan, the Bohai Sea in the south, the Yanshan Mountain in the northwest, the Liaoxi Corridor to the north, the terrain is dangerous, it is the location of the ancient Jieshi, the historian also calls it the 'Jieshi Road', the Sui Kaihuang built the Yuguan City here. Before the loss of the Sixteen Prefectures of Yanyun, Ji Liao was divided here. Because it is located in the horn of the mountains and seas, it is the place of the back water, although the Khitan and Jurchen were good at cavalry warfare in the past, they were not accustomed to water, and the north and south did not use many troops here, but now they are different. Liao and Jin have already crossed the Great Wall, and use more Han people, gradually familiar with water warfare, if the two sides are hostile sides, here can be advanced by land and water, there is no longer the risk of backwater, it is bound to become an offensive and defensive fortress, more important to the soldiers. Recently, this pass was first lost to Liao, and then it was obtained by gold. We are passing through there on our journey, and you should be more aware of the presence of the scene. ”

The Yuguan in Xin Zan's mouth is also called Yuguan, which is the Shanhaiguan known in later generations, and its status is becoming more and more important, and it is known as the first pass in the world.

"During the reign of Emperor Kaihuang of the Sui Dynasty, Linyu Pass was set up. During the Sui Daye period, it was placed in the Chongqing Palace. In September of the 14th year of Hongwu in the Ming Dynasty, Xu Da placed Shanhaiwei in the present-day Shanhaiguan, and moved the "pass" of Yuguan to Shanhaiguan, and moved Yuguan to Shenhe, still using its name. Merge Dongxinzhai Township, Fengzhuang Township, and Yuguan Township to Yuguan Township. In later generations, Shangxu Zhuang Township was merged. Funing County was withdrawn from the county and set up districts, and Yuguan Town belonged to Funing District.

"There is also a beautiful legend here,

There is a happy mouth here, and there is a happy mouth and a poem

The child is cold and undresses and caresses again, and the child is hungry and pushes the food.

Grow up and go far away from the country, and never return.

When he went, he went to the northeast and went straight out of Yuguan to Liaoshui.

The white-headed man is with the shadows, and the mountains and rivers are thousands of miles.

The Heavenly Sect met here, and the father said that my son fell from the sky.

Laughing and dying of happiness, who is in love.

The official family has not opened the border, and it is better to live together and die together.

The mountains and clouds are desert and the wind is blowing, and the mountains and mounds know how many autumns.

At that time, I couldn't bear to be happy, and today I am sad for a thousand years.

The virgin was turned into stone, and she was reluctant to be alone for the rest of her life.

The cold shadow of Qingjiang is long, and there is no news from pedestrians.

Yanshan can go southwest from Xifengkou to the westernmost head, and here is the ditch and the Taihang Mountain are opposite, and Juyongguan is set up here again since ancient times. This is recorded in the "Lü's Spring and Autumn Period" and "Huainan Zi Biography" that "there are nine stops in the world, and one of them is Yong", and "Detailed Records of the Earth" has "Taihang Eight Mountains, and its eighth is the military capital", and the military capital is another name for Juyongguan. As early as the Spring and Autumn Period and the Warring States Period, the Yan State controlled this mouth. When it belonged to Liao, it was guarded with strong soldiers. During the Xuanhe period of this dynasty, the Jin people invaded the Liao State, relying on the seizure of this pass and going south, and then successfully entering Yanjing. ”

At this time, Xin Zan had already talked about the Guangou and Juyong Pass of Yanshan, turned his head and turned his face to point with his hand, and had turned to the direction of Taihang Mountain: "Taihang Mountain is located at the boundary between Jin and Hebei, stretching for thousands of miles, among which hundreds of hills and ridges are connected to each other, thousands of peaks stand tall, and thousands of ravines are deep and steep. Taihang Mountain is cut off by many rivers such as Qin River water, Dan River water, Zhanghe River water, Hutuo River water, Tang River water, Sanggan River water and other water systems from south to north, thus forming countless canyons, the famous ones alone have Yiguan Cheng, Taihang Cheng, Bai Cheng, Fukou Cheng, Jing Cheng, Flying Fox Cheng, Puyin Cheng, Jundu Cheng and other eight Cheng, have always been called Taihang Eight Shan, are important military passes. The reason why this line has been very frequent since ancient times is inseparable from the reasons for the dangerous terrain mentioned above.

"Then to the southwest of Taihang, the remnant of the middle of the strip mountain, it across the Yellow River and the northeast of the Qinling Mountains of the remnant of the mountain opposite, but also around the most famous western Henan corridor. This area is centered on Luoyang, east to Xingyang, west to Tongguan, east and west respectively connect Kanto and Kansai, since ancient times is the key link between the east and west of the Central Plains. Through this important passage, you can occupy Guanzhong, which has 800 miles of Qinchuan River to the west, and you can directly participate in the Central Plains by going east. Xiang Yu's annihilation of Qin at the end of Qin, Chu did not fight for hegemony in the Chu-Han War, Dong Zhuo's rebellion at the end of the Han Dynasty, Li Shimin's elimination of Wang Shichong in the Sui and Tang dynasties, and the Anshi Rebellion in the middle of the Tang Dynasty have always been like this.

"The Central Plains from the Taihang Mountains over the West Henan Corridor and then look south, there are Bear's Ears Mountain, Waifang Mountain, Funiu Mountain, Tongbai Mountain, Dabie Mountain and other mountains around, and those Funiu Mountain, Waifang Mountain, Bear's Ears Mountain, etc. are the remnants of the Qinling Mountains, to the southwest is backed by the Great Qinling Mountains, the whole situation presents a fan-shaped distribution to the northeast, the more you go inside, the more lofty mountains and mountains, the high and dangerous to be able not to cross, these also show the importance of important passes.

"In particular, the Funiu Mountain and the Tongbai Mountain, one is in the west, the other is distributed in the east, the two mountains look at each other in the distance, just like the two gates from the Central Plains to the south to Jingchu, especially the Nanyang and Xiangyang, and respectively clamp the entrance and exit from north to south, from south to north, the geographical location is particularly important."

When he said this, Xin Zan sighed deeply and said: "It's a pity that a few years ago, the Jin State invaded the Song Dynasty in the south, resulting in the fall of most of the land area of the Great Song Dynasty. It's a pity that the six counties of Xiangyang, to the west can connect Qin and Shu, to the east and can overlook Wuyue, you can attack into the Central Plains, and you can shield the land of Zhuhu Guang when you retreat, this place is opposite to the Jin country across the Huai River and Qinling, and now it has become the serious gateway of the Great Song Dynasty to face the Central Plains.

"Tongbai Mountain, located in Henan Province, China, most of the north side of its main ridge is in Henan Province, which is the transition zone from Qinling Mountains to Dabie Mountain, and belongs to the western section of Huaiyang Mountain Range, with a northwest-southeast trend. The narrow sense of Tongbai Mountain is a guide to the area centered on Taibaiding in the south of Tongbai County. Tongbai Mountain in a broad sense, or Tongbai Mountain Range, refers to the vast mountainous area that starts from the eastern edge of the Nanyang Basin, reaches Wushengguan in the southeast, and reaches Guangshui, Suizhou and Zaoyang in Hubei in the southwest, and connects with Dabie Mountain in the east. The mountain range extends in the northwest-southeast direction, has always been "more dangerous than Huashan, and the Yellow Mountain is showy, it is the traffic obstacle between Tongbai, Xinyang and Suizhou, and the Pingjing Pass and Wusheng Pass between the mountains are the traffic holes, and the strategic place. ”
