Emperor Xuan of the Northern Zhou Dynasty, Yuwen Yun, was violent and dissolute by nature, indulged in drinking and sex, and killed loyal people indiscriminately, which made the people of the court and the public panic. Only one year after he ascended the throne, he became tired of government affairs and passed the throne to the seven-year-old prince Yuwen Chan. He proclaimed himself "Emperor Tianyuan" and lived in the harem to enjoy himself. In just one year, he died suddenly due to excessive sexual indulgence at the age of only twenty-two.
The young emperor was under suspicion, so his relative Yang Jian entered the court under the guise of a posthumous edict and used his power to control the military and political power. He forced the young emperor to abdicate and usurped the Zhou Dynasty and established the Sui Dynasty, which was Emperor Wen of the Sui Dynasty. He worked hard to govern and eradicate bad governance. He wiped out all the separatist forces in just nine years, ended hundreds of years of division and chaos, and completed the reunification of the country.
When the Sui Dynasty reached Yang Guang, he planned to seize power and depose the prince Yang Yong. After he came to the throne, he engaged in aggressive military activities, massive construction projects, the construction of the Grand Canal, and frequent military campaigns. The heavy corvee military service exhausted the people's strength. People all over the world revolted, and the Sui Dynasty quickly collapsed. Li Yuan, who was left behind in Taiyuan, took advantage of the situation and raised troops. With his talents and general strategies, he pacified the heroes and established the Tang Dynasty and unified the world in eleven years.
After three hundred years of national destiny, the Tang Dynasty created a glorious and prosperous era in ancient China. In the early period of political clarity, the rule of Zhenguan and the prosperous Kaiyuan era were established successively. The national power was unprecedentedly strong, the economy was prosperous, the treasury was full, the imperial examination system was becoming increasingly perfect, and the ethnic integration continued to deepen. The Tang Dynasty upheld an open and inclusive attitude, had frequent foreign exchanges, and attracted thousands of people from all over the world, showing its aura of being a great nation. Although it suffered from the Anshi Rebellion in the middle and later periods and fell into the predicament of separatist vassal rule and eunuch monopoly, it made remarkable achievements in the fields of literature, art, science and technology, and Tang poetry has been passed down through the ages. The Tang Dynasty, with its strong national power, splendid culture, and far-reaching institutional influence, has achieved eternal legend!
