Actually, the reason is not complicated. Let me briefly talk about my personal views:
First, Liu Xiu, a descendant of the royal family in the Western Han Dynasty, was originally a descendant of the Han Dynasty. His body is full of the blood of the royal family in the Western Han Dynasty. Liu Xiu himself is the ninth grandson of Liu Bang, Emperor Wu of the Han Dynasty, and the third son of Liu Qin, the magistrate of Jiyang County.
The reason why Liu Xiu settled in Nanyang was that his sixth ancestor, Liu Fa, the son of Emperor Jing of Han Dynasty, was sealed in Nanyang. However, by Liu Xiu's generation, the inheritance of the title had ended, and his father Liu Qin was just a county magistrate. Fortunately, his father Liu Qin married a rich daughter, Hu Yang, the mother of Emperor Guangwu, whose maiden name was Fan Xiandu.
Legend has it that when Liu Xiu was born, it was auspicious. Just like when Nezha was born, the family would glow red. People at that time said it was a good sign. Just then, a nine-eared rice grew in the field of Jiyang County, so Liu Qin named his son Xiu. According to Shuo Wen Jie Zi, the original meaning of "Xiu" is that plants are heading and flowering, and there are performances ... Oh, no, it's great.
Xiao Liuxiu's life is particularly bumpy. His parents died, and he became an orphan at the age of 9. He and his brother Ada are in foster care with his uncle Liu Liang. Wang Mang usurped the Han Dynasty to establish a new dynasty, and Liu changed his surname. His uncle Ada always wanted to restore the Han family, so he made friends with all the heroes in the world to prepare for the future. At that time, in addition to reading, Liu Xiu also liked farming. Uncle Ada often makes fun of Liu Xiu's lack of ambition.
At the age of 20, Liu Xiu went to Chang 'an to study. At that time, there was a famous man named Cai Shaogong in Xinye, who was good at divination. In fact, he was a fortune teller. Now there is a fashionable name called psychological sand table. Cai Shaogong once said to his followers: "According to my research on divination, the future son of heaven will be Liu Xiu."
Don't get me wrong, what Cai Shaogong said about Liu Xiu is not what we said about Liu Xiu, but a Buddhist Liu Xiu, who happens to have the same name as Liu Xiu. Unexpectedly, Liu Xiu, who stood by, heard this and said with a smile, "How do you know that the future son of heaven is not me? My name is Liu Xiu, too.
Second, people's hearts moved to the Han and New Dynasties, and the son of Wang Mang was too advanced in his idea of governing the country, and came up with a series of new policies, which were not widely implemented until the 20th century. This is a problem. People's ideas are too old. How can they catch up with Wang Mang, the son of crossing?
Therefore, Wang Mang thinks that the policy is quite good, which makes the people in the world complain a lot and people's grievances boil. The new dynasty gradually lost the hearts of the people, and the people missed the former Han Dynasty one after another, thinking that the old policy was still good. This guy is too reckless.
In short, people all over the world still have a sense of belonging to the Western Han Dynasty. Troops are constantly being attacked all over the country, all under the banner of the Han Dynasty, which has a very strong cohesion. As a relative of the royal family in the Western Han Dynasty, Liu Xiu started his army. There is no reason not to use the banner of "Han" unless he is kicked in the brain by a donkey.
Nanyang Wancheng was a clan of the Li family at that time. Li Tong of the Li family didn't know where he heard the saying "Liu Zhifu, Li Zhifu", so he took the initiative to make friends and wanted to have a business uprising together. Liu Xiu was still modest at that time, and felt that he would only plow and study, unlike his brother Ada, who would make friends. He can't do it alone. If the brothers work together, maybe he can do great things.
As soon as the two brothers combined, they decided that since there was support, let's start fighting.
Then they began to recruit, and the people in Nanyang were very afraid. They think that rebellion is a felony after all, and the future is uncertain. Although it is difficult now, I can survive if I live, and my head will be gone if I fail to resist, so I can't live.
Just as everyone hesitated, Liu Xiu, the son of the plane, appeared in front of everyone wearing a military crown and a shirt. "Liu Xiu has always been cautious, but now she has turned against him," said Wan Ren in great shock. It seems that this matter is still reliable. " As a result, people all went to Liu Xiu. In 22 AD, 1 1 month, Liu Xiu and his brother Ada rose up in Wancheng. Liu was 28 years old.
Third, he and his brother attacked the city and pulled out the land in the name of Han, and their fame in the uprising army became higher and higher, which caused some people's fear and suspicion.
In order to weaken the brothers' power, a force in the uprising army established Liu as emperor. The man's name is Liu Xuan. Note that its name is Liu Xuan, not Liu Xuande. Let's not confuse.
Liu Xuan didn't make any contribution to this man, and he knew it, so he was very nervous and climbed onto the foundation on thin ice, so he was called Xiandi. Soon, in order to consolidate his authority, Liu Xuan killed Ada, Liu Xiu's younger brother.
Liu Xiu is very sad. But he can hold his breath. He knew that revenge for his brother at once would not only kill himself, but also split the rebels, and the great cause of reunification would be in vain.
He choked back his sadness and became more humble before Liu Xuan. Seeing such honesty, Liu relented. Instead of killing Liu Xiu, he felt a little guilty about him.
Insurgents from all walks of life were on a roll, and soon they broke into the capital Chang 'an, where Wang Mang was killed and the new dynasty perished. Liu Xuan, Qin Shihuang, made Luoyang its capital.
When Liu Xiu settled Luoyang as an official, he always wore the traditional official clothes of the Western Han Dynasty. He was handsome and dignified. The generals of Liu Xuan, the first emperor, were dressed in confusion and dragged their feet, without paying attention. Some even wear women's clothes to work, which looks funny beyond words. Many people can't help but respect Liu Xiu. The old ministers said with tears: "This is the demeanor that a big man should have!"
People pinned their hopes for reviving the Han Dynasty on Liu Xiu.
Liu Xuan did not have the ability to govern the country, so Liu Xiu complied with the people's hearts. With his military genius and noble personal character, he first fought Kunyang and then recovered Hebei, leading all the way. At that time, Liu Xiu made remarkable achievements and was placed high hopes in the minds of soldiers.
Liu Xiuqi and Liu Xiujun fought against Wang Mang, both adhering to a principle, which is to revitalize the Han Dynasty. Therefore, although Liu Xiu was the founding king of the Eastern Han Dynasty, he also continued the Han Dynasty and restored the glory of the Han family. His success, of course, is inseparable from his outstanding personal ability, but more inseparable from the appeal of the Han Dynasty. So it is natural that he founded the country in the name of the Han Dynasty.
