In the Sui Dynasty, officials were elected. From 1 1 month to the end of the following spring, everyone was snapped up. At the end of the first year of Zhenguan (627), Liu, assistant minister of the official department, invited him to listen to The Four Seasons in the Future. He wrote it in que, which people thought was convenient. In the early Tang Dynasty, because of the war, literati were unwilling to be officials, so there were insufficient officials. At that time, the commanders of Shangshu Province ran for election in various states, and the state government and the envoys who served the imperial edict used red messengers as official posts. At this point, this practice was abolished and candidates were ordered to run in Shangshu Province. In the first year of Zhenguan, there were more than 7,000 candidates, and Liu was an official, each in his place. Because there was a lack of food in Guanzhong at that time, Emperor Taizong ordered some people to run to Luozhou. Taizong said, "Officials have people, but not many people." Party and provincial central officials were ordered to set out, leaving only 643 civil and military officials.

Uighur suffered a crushing defeat.

When the East Turkistan was powerful, various parts of Chile (or Tiele) were scattered in Mobei, including Xueyantuo, Uighur, Dubo, Gu Li Gan, Dolange, Tongluo, Shigu, Banougu, Sijie, Hun, Hu Xue, Jiedi, Qiju and Xiaobai. Khan in Sana 'a, a western Turk, is powerful, and all the ministers in Chile belong to him. Sana 'a levied excessive taxes on them, and various ministries complained bitterly. Sana 'a killed more than 100 canal commanders, and Chilean ministries rebelled one after another, recommending Che cold brother as easy but not true, and living in the north of the mountain. He also blamed the loss of Xue Yantuo's bowl on Xiao Khan, who lives in the north of Yanmei Mountain. When the West Turkic Army shot Khan again, the Second Division removed the title of Khan and surrendered to him. The six Uighur tribes living in Dujunshan originally belonged to the East Turkic Li Jiekhan, while the strength of the West Turkic Yehukhan weakened, and more than 70,000 handsome tribes surrendered to Li Jiekhan eastward. Soon, the political situation in Valerian was chaotic, and Xue Yantuo defected from Uighur and Banyegu. Valerie sent her brother's son, Desire Valley, to take 100,000 cavalry to crusade, and Uighur Chief Bodhisattva took 5,000 cavalry to attack the Desire Valley in Majishan. Uighur suffered a crushing defeat and set up the Valley of Desire. The Bodhisattva pursued the Valley of Desire to Tianshan Mountain, captured most of the military forces in the Valley of Desire, and greatly boosted the Uighur forces. Xue Yantuo also breached Radio 4 in Jie Li. Valeriana is weaker, the snow is several feet deep and the people are hungry. Fearing the attack of the Tang Dynasty, Jieli Khan led troops to live in Shuozhou. At the beginning of the second year of Zhenguan (628), Zheng Yuanshou, the Cracked Han who came back from preaching in Turkey, requested to send troops to attack the Turks, and the ministers agreed. It is unjust for Emperor Taizong to form an alliance with the Turks with a new idea, but it is enough.

Jie Li Khan's Resistance to West Turkestan and Tang Qin.

At the end of the first year of Zhenguan (627), Zhu Zhen of Yehu Khan in West Turkic sent Li Daoli to Tang to marry the princess, and donated tens of thousands of belts and five thousand war horses. Valerie Khan of East Turkistan did not want good relations between the two countries, so she invaded the country many times and sent someone to threaten Tongye Hu, claiming that "to marry Princess Tang, you must pass through the territory of East Turkistan". Tong Yehu was worried and failed to get married.

In 627, the Byzantine (Eastern Roman Empire) Chilalio led an army at the former site of Nineveh, the gateway of Taixi Peak, the Persian capital, and severely damaged the Persian army.
