On June 4th, 9 th, Wude, Tang Gaozu, Li Shimin, the king of Qin, led his cronies to launch a campaign to kill Li Jiancheng, the Crown Prince, and Li Yuanji, the king of Qi. After the initial success, Li Shimin immediately sent his valiant soldier Wei Chijingd《旧唐书》, which is very interesting to read: &”;Respect Germany and hold a spear until Gaozu.&”;. Gaozu was frightened and asked,&; Who is the insurrection today? Why did you come here?&; He said,&; The king of Qin rebelled against the prince and the king of Qi, and dispatch troops punished him. For fear of your majesty&;s alarm, he sent his officials to stay in the guard.&; High-impedance means peace. Nanya, Beimen, the soldiers and horses, and the Second Palace refused to fight, and Jingde asked them to surrender their hands, so that all the soldiers were punished by the King of Qin, so the internal and external decisions were made. &”;It can be seen that Wei Chijingde, dressed in uniform, came to Tang Gaozu. From this moment on, Tang Gaozu Tang gaozu was actually under control and house arrest, and Li Shimin gave orders through Tang gaozu, which was very cl《旧唐书》 said that when Tang Gaozu heard the news, he was shocked and asked Pei Ji and others, &”;What happened today?&”; Xiao Yu and Chen Shuda suggested: &”;The King of Qin has made great contributions to the world and returned home. If he is given Yuan Liang and entrusted with state affairs, your majesty will be relieved and the whole life will naturally be at peace.&”; It means letting Tang Gaozu hand over power to Li Shimin, so that Tang Gaozu can relieve itself of its burden, and the country can be at peace. Tang Gaozu was very sensible and said, &”;Good! This is also my ambition. &”; Then he ordered Li Shimin to be called in and caressed him, saying, &”;I&;ve come recently, and I&;m a little confused.&”; Li Shimin burst into tears, &”;wailing for a long time&”;. No matter whether Tang gaozu is active, voluntary or helpless, from this day on, Li Shimin has actually mastered the power. Five days later, Tang gaozu officially confirmed Li Shimin as the Crown Prince, saying that &”;all ordinary governments are determined&”; and at the same time he granted amnesty to the world. At the same time, the power distribution of Li Shimin Group is also unfolding in sequence. On the day of July, Gao Shilian was announced as the assistant, Fang Xuanling as the secretariat, Xiao Yu as the left servant of Shangshu, Yang Gongren as the shepherd of Yongzhou, Changsun Wuji as the official minister, Du Ruhui as the minister of war, Yu Wenshi as the secretariat, and Deyi as the right servant of Shangshu. On the day of Guihai in August, Tang Gaozu Li Yuan sent a letter to the Crown Prince Li Shimin, and Li Shimin was the emperor in the Xiande Hall of the Eastern Palace, and Li Yuan was honored as the emperor&;s father. In April of the third year of Zhenguan, Emperor Tang gaozu moved out of the palace and moved to Hongyi Palace, and Emperor Taizong Li Shimin officially began to listen to politics in Taiji Hall. This means that Emperor Taizong has firmly grasped the power and can relax his control over the emperor&;s father. Interestingly, Hongyi Palace was built by Tang Gaozu in Wude for five years in recognition of Li Shimin&;s contribution, in the west of Miyagi. In the eighth year of Wude, Tang Gaozu was lucky once and ordered to build a fake landscape in Hongyi Palace. Unexpectedly, a few years later, the father and son were translocated, and Hongyi Palace was renamed Tai &;an Palace (also known as Da &;an Palace). Some of Tang gaozu&;s youngest sons followed him to live in Tai &;an Palac《旧唐书》 mentioned that Emperor Taizong sent Shang Palace to bring food to the Emperor&;s father every morning and evening. Li Yuanming, the eighteen sons of Li Yuan, was only ten years old. People around him told him, &”;When you see Shanggong, you should be polite.&”; Li Yuanming said, &”;They are my second brother.Maids, why should I salute them? &”;Treat the emperor&;s father, Li Shimin won&;t be as filial as Song Xiaozong later treated the emperor&;s father Song Gaozong. After six years of Zhenguan, Ma Zhou, the supervisor, got a little tired of it. I put forward some suggestions about the emperor&;s father, from which I can read a little meaning. Ma Zhou believes that the Tai &;an Palace is too humble and small, and it is located outside the city, so that the supreme emperor&;s father can live there and be seen by envoys from all over the world, which has a bad influence. Therefore, a gatehouse should be built for Tai &;an Palace, and a mound should be built around it to show the lofty style of the palace and the emperor&;s filial piety. At that time, Emperor Taizong was planning to go to the palace for the summer. Ma Zhou thinks that the emperor is old, and the emperor should greet his meals and daily life morning and night. Moreover, it is not appropriate for the emperor&;s father to stay in the sultry Chang &;an and the emperor himself to go to a cool place for the summer. On the whole, Li Yuan, who was taken away from the throne, is very wise and honest, rarely shows up, &”;wandering in the heart and being frugal&”;, and there are not many ideas and attempts. Therefore, father and son can live in peace and he can spend his old age safely. As for whether Tang gaozu is happy or not, it depends on his personal subjective wishes. If he is obsessed with the supremacy of the old days and does not forget the descendants who died in the war, he will certainly be unhappy. If he can accept the reality frankly, stop fantasizing, support the elderly with peace of mind and cultivate his true nature, his life should be good. The more formal activities of the emperor&;s father are rarely recorded in the history books. In March of the eighth year of Zhenguan, Emperor Taizong hosted a banquet for the emissary of the West Turkic in the Hall of Two Instruments. The Emperor&;s Father and Changsun Wuji were also present. The emperor&;s father praised Changsun Wuji, saying, &”;Today&;s barbarians are obedient, which has never existed in ancient times.&”; Changsun Wuji toasted the emperor&;s father, who was so pleased that he gave the wine to Emperor Taizong. Holding wine, Emperor Taizong came to worship the Emperor Taizong again, weeping and saying, &”;The people are safe, and the four countries are salty. They are all obedient to the imperial edict. How can I help them!&”; In the same year, Tai Shang Huang attended a military in the west of the city, and then held a banquet in Weiyang Palace, attended by officials above the third grade in the DPRK. Turkic Khan danced, the chief of South Vietnam chanted poems, and the Emperor Taizong laughed and praised: &”;The Hu and Yue families have never existed since ancient times.&”; Emperor Taizong held a cup to propose a toast to the emperor&;s father. Looking back on his achievements in recent years, he said, &”;All the intelligence of this minister is from heaven.&”; The emperor&;s father was overjoyed, and his ministers shouted long live. Everyone was very happy that day. At this point, the life of Emperor Tang gaozu has reached the final stage. In May of the following year, Li Yuan died in the front hall of Tai &;an Palace, at the age of seventy (or seventy-one), and was buried in Xianling.
