When it comes to the Tang Dynasty, the first person that comes to mind is Tang Taizong Li Shimin, who often subconsciously ignores Li Yuan, the real founder of the Tang Dynasty. This is mainly because on the one hand, Li Shimin seized the throne through improper means, and on the other hand, it is indeed Li Shimin's exploits that cover up Li Yuan's brilliance.
In fact, Li Yuan was a very capable and ambitious person, and his ambition was unmistakable long before he started his army. Li Yuan's four sons, as can be seen from their names, his ambitions are obvious.
Li Yuan's eldest son, Li Jiancheng, took the "completion" in the hope that he could "establish the imperial program and achieve great deeds.", and Li Jiancheng did not live up to Li Yuan's painstaking heart. Before the Taiyuan army was raised, Li Yuan's ministers persuaded Li Yuan to raise an army, but Li Yuan did not agree, until Li Jiancheng returned to Taiyuan and personally met Li Yuan, li Yuan agreed to raise an army. When there was no great chaos in the world, Li Yuan included his ambitions by naming his son. Later, Li Yuan finally unified the world and established the Tang Dynasty, which was very open and powerful in history, and the trajectory of his life was like the name of the eldest son, very successful.
Li Yuan's vice-chancellor is the famous Li Shimin, and "Shimin" means "Ji Shi'anmin". And Li Yuan, after pacifying the world to establishing datang, also worked towards this aspect. The Tang Dynasty established a set of effective political systems and formulated various policies for recuperation. With his efforts, the world gradually calmed down, and the economy and population made great progress.
Li Yuan's third son is called Li Xuanba, but he is called Li Yuanba in many film and television dramas. It is said that at that time, Li Yuan was just degraded to Taiyuan, but on the way Li Yuan's wife was facing childbirth, fortunately there was a Taoist temple nearby, which was born safely, because he was born in the Taoist Temple, so he named it "Xuanba", which means "Xuanmen's Hegemony". After the establishment of the Tang Dynasty, Taoism indeed became the state religion of the Tang Dynasty.
Li Yuan's younger son was named Li Yuanji, and the word "Yuan" had a special meaning in ancient times. The first gua of "Qian" in "Zhou Yi" is "Yuan Henry Zhen", "Yuan" symbolizes the beginning of everything, and the clothes worn by the emperor are also called "Yuan Clothes", indicating Li Yuan's ambition to establish a new order and unify the world, and finally he also did this. However, his son Li Yuanji was not so lucky, Li Shimin launched the "Xuanwumen Revolution", Li Yuanji and Li Jiancheng both died, and finally Li Yuan gave up the throne in his later years, and the Tang Dynasty opened a new chapter under the leadership of Li Shimin.
