AD 1644, the Jiashen year of the lunar calendar.
In this year, there were four era names in China at the same time - the 17th year of Chongzhen, the first year of Yongchang, the first year of Shunzhi, and the first year of Daxi Destiny.
In the first month of the first month, Li Zicheng founded the country in Xi'an. The country was named Dashun and the reign was named Yongchang. When he went to Beijing, he thought that the world was already in his possession.
In March, Chongzhen hanged himself in Meishan. This emperor, who had served diligently for seventeen years, wrote his last edict on his clothes before his death - he said, "I will not be able to see my ancestors before I die."
In April, Wu Sangui made a decision in Shanhaiguan. This decision allowed Dorgon's Eight Banners cavalry to enter the Central Plains, and also changed China's destiny for nearly three hundred years.
In May, Dorgon entered the Forbidden City. Over in Nanjing, Prince Fu, who only indulged in wine and sex, was hurriedly raised to the throne. Shi Kefa asked for orders to supervise Yangzhou, but he could not mobilize the soldiers of the four towns in Jiangbei.
After autumn, the blood in Shanhaiguan has not dried yet. Li Zicheng defended himself at Tongguan, Zhang Xianzhong proclaimed himself emperor in Chengdu, and the Donglin Party and the remaining eunuchs fought to the death in the Hongguang Court in Nanjing. Dorgon stood in front of Wuying Hall, looking at the land he had just stepped into - dilapidated, but magnificent.
This is the first year of "Yongchang".
The word "Yongchang" has become the biggest black humor this year. The person with this reign name served as emperor for forty-two days and was then driven out of Beijing. The empire he left behind was buried with him in Jiugong Mountain, Hubei four hundred days later.
This is the most intensive 365 days in Chinese history.
Two emperors died, four political regimes stood side by side, a battle was fought to determine the fate of the country, and countless little people were crushed into powder.
