1. Encircling Wei to save Zhao, reflecting historical facts: Pang Juanbing encircled Wei to save Zhao, Sun Bin ordered the Qi army to point to Wei Zhiliang, Pang Juan had to return to Weidu to save Zhao's siege, and Zhao's siege was lifted. Revelation: Don't blindly deal with everything directly. You can achieve the desired results from the side or by borrowing the power of others. The retreat of the three families reflects a historical fact: during Chu Jin's hegemony, Zhong Er and Jin Wengong, because of the kindness of the King of Chu, ordered the Jin army to take the initiative to retreat in front of the Chu army to repay the kindness of the King of Chu. Revelation: Gratitude is a virtue that cannot be forgotten at any time. The way of falsely cutting Guo reflects such a historical fact: Jin wanted to attack Guo, borrowed it, and promised to be virtuous after destroying Guo. I believed it and promised Kim. Who knows that the State of Jin destroyed the State of Guo, and on the way back, it destroyed the State of Yu. Revelation: Yu Guojun ignored the fact that his lips were dead and his teeth were cold. Yu and Guo are both small and weak countries, and Jin is a strong country. If the two weak countries form an alliance first, and if they can understand the situation clearly, they will not borrow money and lead to the country's demise. 2. Legend of the Origin of the Descendants of the Yellow Emperor More than 4,000 years ago, there were many clan tribes living in the Yangtze River and Yellow River basins in China, among which the most famous ones were Huangdi tribe, Yan Di tribe and Chiyou tribe. Huangdi tribe lived in the northwest of Shaanxi Province today, then moved eastward, and finally settled in the mountainous area around Zhuolu in Hebei Province, leading a nomadic life. Yan Di tribe is active in Shaanxi from Weihe River basin to the middle reaches of the Yellow River. The Chiyou tribe, also known as the "Jiuli nationality", lives in the eastern part of China, that is, today's Shandong and Henan. During the interaction of these three tribes, several major wars took place in the northern part of Hebei Province today.

After the Yan Di tribe entered the middle reaches of the Yellow River from the Weihe River basin, it had a long-term conflict with the Chiyou tribe. After being defeated by Chiyou, Emperor Yan fled to Zhuolu, Hebei Province, and took refuge in Huangdi tribe. Later, the two tribes joined forces to fight Chiyou in Zhuolu. Chiyou was defeated and killed by Huangdi tribe, and Huangdi won. This is the famous "Battle of Zhuolu" in history books.

The Yellow Emperor adopted a policy of appeasement to the members of Chiyou tribe, and the members of Chiyou tribe who stayed in the north joined the Yanhuang tribe. When other tribes heard that Chiyou had died, they all worshipped the Yellow Emperor. Everyone supported him to be the son of heaven, and the Yellow Emperor built his capital in Zhuolu.

After defeating Chiyou, the Yan Di tribe fought for hegemony, and there was a big conflict with the Huangdi tribe. Two tribes, Yan Di and Huangdi, fought another war in Hanquan (now Huailai, Hebei Province). As a result, Yan Di was defeated and surrendered to the Huangdi tribe. Later, their descendants developed from Hebei to the south, entered the Yellow River basin and settled in the Central Plains. After living together for a long time, * * * multiplied together and merged with each other, and * * * together formed the ancient residents in the Central Plains of China, laying a historical foundation for the later Chinese people. In the long historical development process, due to the relatively strong power and high culture of Huangdi tribe, many inventions and creations of working people in primitive society were recorded in the name of Huangdi, who became the representative of Central Plains culture. Since then, this tribe has gradually developed, and residents of different ancestors living in the Central Plains consider themselves descendants of the Yellow Emperor. After the Spring and Autumn Period (770-476 BC), these residents called themselves Huaxia nationality, and after the Han Dynasty they were called Han nationality. Later Han people regarded the Yellow Emperor as their ancestors and called themselves "descendants of the Yellow Emperor".

In the early years of the Western Zhou Dynasty (BC 1 1 century), Zhou Wuwang's younger brother Zhou Gongdan founded Luoyi (now Luoyang City, Henan Province), and regarded the Central Plains as the center of the world, so he called it "Middle Earth". Huaxia people live in the Central Plains, so they call this area "China". Later, with the continuous integration of China and other ethnic groups, the scope of China's activities continued to expand, and the highly developed Chinese culture gradually spread to all parts of the country. "China" has gradually become the name representing the whole of China, and "descendants of the Chinese people" has a broader meaning.

Some people say that China refers to Huashan Mountain, and summer refers to the water in summer, that is, Hanshui River. Do Chinese sons and daughters refer to the descendants bred by the distant ancestors of Hanshui River Basin at the foot of Huashan Mountain in a narrow sense? But as long as we pay attention to the pronunciation in the south, we will understand that the pronunciation of "Hua" is "Wa", and Wa refers to "Nuwa"; The pronunciation of "Xia" is "Xi", which means "Fuxi". China's children are actually Xi's children. In ancient China, the so-called surname was actually a girl's surname. With women, there is a clan, and women are the ancestors of the clan. Therefore, you are ahead of Xi, but in a patriarchal society, things have changed. Because Nvwa 、 Fuxi's time was too far away, China people turned to the descendants of the Chinese people, and the descendants of xi were scattered outside China (that is, what we are talking about now). The battle of Guandu The battle of Guandu The comparison of forces between Cao Cao and Yuan Shao at the front of Guandu should be 1: 4, that is, 20000VS80000. As a result, Cao Cao defeated Yuan Shao. Tell us a simple truth of ancient war: the soldiers and horses did not move, and the food and grass came first. In ancient times, grain and grass were very important. In today's military, it is the logistics supply of both sides that affects the direction of the war situation. Compared with Cao Cao, Battle of Red Cliffs Battle of Red Cliffs boasts an army of 800,000, with an actual strength of 200,000, and has invested nearly 70,000 amphibious troops in Chibi battlefield.

Zhou Yu's elite navy is 30,000, Liu Bei 1 10,000, Liu Qi 1 10,000, and nearly 60,000 land and water troops have invested in Chibi.

As a result, Cao Cao was defeated. In ancient times, it gradually developed into a contest of specialized arms. Although Cao Cao is superior in number, his ultimate goal is to fight against Sun Quan on the road. From the beginning, he ignored the military confrontation on the water. The defeat of Chibi made Cao Cao realize the importance of sailors. From ancient times to the present, the modern army must cooperate with multiple arms to have a better winning rate. Comparison of forces in the battle of Yiling: According to the Records of the Three Kingdoms, Liu Bei led 70,000 to 80,000 Shu and Han armies, most of which were army, and a few water armies were Guan Xingjun stationed in Jiangzhou. While Soochow sent Lu Xun to lead the troops around 50,000. As a result, Liu Bei was defeated. Modern operation should be adapted to local conditions in order to give play to its own advantages.
