Li Yuan's grandfather, Li Hu (李虎), was an official in Western Wei and one of the Eight Pillar States of Western Wei, and was later posthumously awarded the title of Duke of Tang. Before the Sui Dynasty, Tai Wei was a senior military official, equivalent to the current Minister of Defense. Li Yuan's father, Li Xun (李昞), was a Northern Zhou dynasty official, the governor of Anzhou, and a general of the Pillar State, and the Duke of Tang. Li Yuan's mother was Emperor Wen of Sui's empress Dowager Gujialuo, the sister of The Lonely Empress was Li Yuan's mother, and Yang Jian, the Sui Emperor of the Sui Dynasty, was Li Yuan's uncle. Empress Dugu was very fond of Li Yuan, and Emperor Wen of Sui was particularly close to Li Yuan. According to historical records, Li Yuan's personality was free, tolerant, and good at making friends, and both noble and lowly people were pleased with him. With such a noble origin, superior environment, and good conduct, Li Yuan's career was very smooth. After Emperor Wen of Sui came to power, Li Yuan was appointed as a military attaché of the Janissaries, responsible for his safety, and later promoted to Assassin Shi, County Shou, Junior Supervisor of the Palace, and Wei Wei Shaoqing. There was a person who was good at looking at his face, saying that he had a heavenly dragon face and could be called emperor in the future, and after Li Yuan heard it, he was very afraid but very proud.

After the reign of the Sui Emperor, in 613, Yang Guang conquered Goguryeo for the second time, and Li Yuan was appointed as the grain inspector. In ancient times, when using soldiers, it was often said that "the soldiers and horses did not move, and the grain and grass went first", which shows the importance of his responsibilities. However, yang Xuangan, the son of Yang Su, the rear chancellor, suddenly rebelled, and Li Yuan was ordered to defend present-day Qingyang Commandery in Gansu. During the zhenshou period, he made friends with haojie in the world, which caused great dissatisfaction and suspicion among the Sui Emperor, so he ordered him to report for duty, and in order to protect himself and save himself, Li Yuan said that he was ill and that the Sui Emperor had a murderous heart. Li Yuan was deeply frightened, and in order to dispel Yang Guang's suspicions, he drank uncontrollably all day long, and in 615 AD, Li Yuan was appointed as a consolation envoy in Hedong, Shanxi, and defeated the peasant rebel army of His mother Duan'er. The following year, he defeated the Turkic invasion, which deeply satisfied the Sui Emperor.

In 617, Li Yuan was appointed as the retainer of Taiyuan, which laid a solid foundation for his future great deeds. During this period, the Sui Dynasty was already in turmoil and war. Sui and Tang Dynasties once described that there were 36 anti-king, 72 roads of smoke and dust, pulling on the banner of rebellion, although the novel has a derivative element, but it fully shows that the war of the peasant rebel army has engulfed the Sui Dynasty. During this period, in the process of suppressing the peasant rebel army, Li Yuan constantly recruited rebels and expanded his strength. After the Sui Emperor Yang Guang was isolated in Jiangdu, Li Shimin decided to rebel without informing Li Yuan. But afraid that his father Li Yuan would oppose, he conspired with Pei Huan and selected a beautiful woman from the Jin Palace to spend the night with Li Yuan, and only later told him that this was a person from the Jin Palace, Li Yuan was horrified, and Li Shimin told his father that at present, the Sui Mountains and mountains were in turmoil, only in the middle of the night, so he reported the whole plan to him, Li Yuan still disagreed at first, and later agreed to raise an army under the repeated persuasion of the people of the world. In 617, Li Yuan led 30,000 elite troops to take Guanzhong directly, which can be said to be a breakthrough, because the military forces of the Sui Dynasty were near Jiangdu. After breaking through Guanzhong, Li Yuan did not claim the title of emperor, but instead supported Yang You, the empress dowager of Yang Guang, as emperor, and the Sui Emperor as emperor of Taishang, forcing Yang You to make himself the King of Tang, the Grand Chancellor, and Shang Shu Ling, and the rest of his sons were rewarded. Until the third month of the lunar calendar in 618, the Sui Emperor committed suicide in Jiangdu, and in May, Li Yuan forced Yang You to take the throne to himself, and Li Yuan called himself Emperor Yu of Chang'an, and the country name was Tang Dynasty! The tang dynasty began.
