When the heavy pages of ancient history are opened, those dynasties that have been sealed by the dust of time are as fascinating as treasures hidden in the long river of history. And these dynasties that have not been recorded in the official history, although they have not left a dazzling mark, but they bear the profound historical imprint of the rise and fall of honor and disgrace.
First, let's focus on the New Dynasty of the Western Han Dynasty, founded by Wang Mang. In the ninth year of AD, Wang Mang ascended to the sky in one step, deposed the crown prince of the Western Han Dynasty, ascended the throne, and established a new dynasty. However, the ambitious emperor was unable to turn the tide of events, and his reform policies and social conflicts intensified, eventually leading to the fall of the new dynasty. Wang Mang tried to strengthen the centralization of power through a series of political and economic reforms, but his policies were strongly opposed by large landowners and the aristocracy. This intensification of contradictions eventually led to the collapse of the new dynasty, making Wang Mang's reign a regrettable period in history.
Wang Mang and in 197 AD, the "Zhong Dynasty" established by Yuan Shu was a bright spot in the late Eastern Han Dynasty. Against the backdrop of turbulent times, Yuan Shu dared to proclaim himself emperor, but his ambitions were eventually crushed by Cao Cao's iron horsemen, leaving behind a thrilling chapter in history. The establishment of the Zhong Dynasty stemmed from the political corruption and corruption of the Eastern Han Dynasty at that time, and Yuan Shu took the opportunity to rise and tried to show his ambition in the troubled times. However, his regime was short-lived, and it quickly fell under strong pressure from Cao Cao, becoming a brief and tragic event in history. 
In addition, we cannot ignore the Huang Qi Dynasty established by Huang Chao in 880 AD, and the Yongle Dynasty led by Fang La in 1120 AD. These two dynasties, one is the wave of peasant uprisings, and the other is the glory of changing dynasties. The Huangchao Uprising was an important event in the peasant uprising at the end of the Tang Dynasty, reflecting the peasants' dissatisfaction and resistance to feudal rule at that time. Fang La's Yongle Dynasty was a peasant uprising in the last years of the Northern Song Dynasty, and Fang La established his own regime centered on Hangzhou in an attempt to overthrow the rule of the Northern Song Dynasty. However, his ambitions were eventually suppressed by the Northern Song Dynasty, and the Yongle Dynasty also became a short memory in the long river of history. 
In 1127 AD, while conquering the land of the Great Song Dynasty and plundering gold and silver treasures, the Jin State also had to establish the Great Chu Dynasty in this conquered land and support the Song minister Zhang Changbang as emperor. However, Zhang Changbang knew that his rebellion against the imperial court would have serious consequences, so he decisively abdicated the throne once he had the opportunity to return to the Great Song Dynasty. It's like a bird that reluctantly returns its corolla after robbing it of its fragrance.
The flame of peasant uprising ignited the flame of hope again and again, but it was also slowly extinguished in the chaotic flames of war. In the long history of 1644 AD, the peasant uprising led by Li Zicheng was like a bright meteor, briefly but brilliantly across the sky, and established the Great Shun Dynasty. However, just as the glory of a meteor cannot last, the Great Shun Dynasty cannot last. The reason for this lies in the failure to reach a solid alliance with the landlord class, just as it is difficult to stand on one foot, and after all, it suffered from the encirclement and suppression of the imperial court and the double blow of the landlord class.
In the end, the struggle between the Great Shun Dynasty and the Qing Dynasty lasted for twenty or thirty years. This struggle is like two turbulent torrents colliding with each other, stirring up countless waves. Although the Great Shun Dynasty gradually declined in this struggle, its influence was far-reaching, like a seed, buried deep in the soil of history, waiting for the future to sprout and grow.
In 1644, Zhang Xianzhong led a peasant uprising and established the Great Western Dynasty. However, the valiant leader was unfortunately shot by a cold arrow during a battle and died heroically. Despite this, his career did not end there, but his right-hand man Sun Kewang and his four righteous sons continued to carry the banner. They established a new regime in Chengdu and fought against the Qing army for more than two decades. In this magnificent history, they have written heroic and magnificent epics with tenacious perseverance and incomparable courage.
However, Wu Sangui's legend has not disappeared because of this. His bravery and his dreams have become legends for future generations. His story tells us that no matter how powerful a hero is, if he loses the hearts of the people, he will only end up in the dust of history. 
Yuan Shikai briefly established the Chinese Empire, however, this regime did not enjoy the approval and support of the people at large. After only 83 days, he was overthrown by the people, because the people's desire for a republican system was far greater than that of a centralized system. This period of historical change reveals the people's deep insight and firm determination to choose a political system. 
Behind these forgotten dynasties are the struggles and sacrifices of a group of ordinary people, and they are stirring historical stories. They are either dreamers, heroes, or schemers, but their existence has left a profound imprint on ancient history and left us a vivid historical picture.
Therefore, while looking through history, let us explore those forgotten dynasties with awe, and feel those who fought for their ideals, because their existence has led to our prosperity and stability today. May these forgotten histories be forever remembered in our hearts and become our guide and inspiration for moving forward.
