Li Shimin's last expedition lasted from February 12th, 645 to March 7th, 646. It lasted for about a year.
Li Shimin's last expedition was against Goguryeo in the year 645. He had fought Yeon Gaesomun in this war. This was the first war between the Tang Dynasty and Goguryeo.
Li Shimin's campaign against Goguryeo was a war that took place between the 18th year of Zhenguan (644) and the 19th year of Zhenguan (645). Li Shimin adopted flexible strategies and tactics, including water and land cooperation, siege of cities, elimination of reinforcements, and psychological attacks. He had conquered ten cities and killed 40,000 people. However, due to Goguryeo's stubborn resistance and harsh climate, Li Shimin was unable to conquer Goguryeo completely. Even so, Li Shimin's campaign had placed a huge military pressure on Goguryeo, weakening its national strength. All in all, Li Shiming had achieved a certain degree of victory in his campaign, but he had not completely conquered Goguryeo.
Li Shimin's expedition to Goguryeo was not completely successful. Even though he had obtained some victories in the battle and conquered ten cities, he ultimately failed to achieve his goal of destroying Goguryeo. When they attacked An City, they encountered strong resistance and were unable to conquer the city. Considering the harsh weather and the difficulty of logistics, Li Shimin had to order the retreat. Thus, although some results were achieved, overall, the Eastern Expedition was not a complete success.
Li Shimin's fief was in the Guanzhong Plain in the west of Shaanxi Province, which was called Qin in ancient times. His title was Duke of Qin, and later, when he was conferred the title of King, he was called the King of Qin. The specific name and location of the fief was not mentioned.
There were several reasons why Li Shimin did not go to Mount Tai. First of all, Li Shimin's idea of governing the country was based on the people and focused on practical results, not form. He was more concerned about the stability of the country and the well-being of the people than the Fengshan ceremony. Secondly, the country under Li Shimin's rule was in the recovery stage after the war. Shandong also experienced war, and the economy and people's lives were facing difficulties. Carrying out the Fengshan ceremony required a lot of manpower and material resources, which might increase the burden on the country and the people. Therefore, Li Shimin considered this point and did not carry out the Fengshan ceremony. In addition, Li Shimin himself had some health problems. He might be worried that climbing Mount Tai would cause a relapse. In summary, Li Shimin did not go to Mount Tai for the sake of governing the country, the state of the country, and personal health.
Li Shimin was the second emperor of the Tang Dynasty. He had made many great achievements during his reign. First, he had achieved glorious military achievements, conquering Goguryeo, the Turks, and other hostile factions, stabilizing the borders.

Secondly, he paid attention to national governance and cultural development, implemented educational reform, established the Imperial College, and promoted the prosperity and development of culture. He also implemented the land equality system and the rent and employment system, which improved the lives of farmers. In addition, he also strengthened foreign exchanges and raised the country's international status. In general, Li Shimin laid a solid foundation for the prosperity and prosperity of the Tang Dynasty with his outstanding military skills and open-minded ideas of governing the country.
Li Shimin was conferred the title of King of Qin because most of his fief was located in the original Qin State. Li Yuan made Li Shimin the king of Qin to give him the greatest benefits, so that he could manage the Guanzhong and Longyou areas in peace and protect the royal family of the Tang Dynasty. Li Shimin was given the title of General of Heavenly Strategy because of his outstanding performance in the battle to pacify Liu Heita. He used this title to consolidate his power. As for Li Shimin's repeated changes to his brother's posthumous title, it was because the posthumous title proposed by the ministers did not conform to Li Shimin's wishes. He hoped that the posthumous title could explain both the good and the bad. As for Li Shimin's other titles and titles, due to the lack of information provided, it was impossible to give a specific answer.
