Li Longji is the third son of Li Dan. According to common sense, he is neither the legitimate heir nor the eldest son. The crown prince and emperor cannot sit with him, but that is a normal situation. If the situation is not normal, everything can be said based on strength.

Li Dan himself did not have outstanding talents, and becoming emperor was purely a stroke of luck. Below, the history encyclopedia editor will bring you a detailed introduction. Let’s take a look together!
The first time he ascended the throne was brought in by his mother Wu Zetian, and the second time he ascended the throne was a coup launched by his son and sister to push him to power – his own throne was taken by his son Li Longji. If he passed the throne to his eldest or second son, would they dare to take it? Can Li Longji agree?
In fact, when Li Dan first ascended to the throne, he was conferred the title of Crown Prince by his eldest son Li Chengqi. After Li Dan was demoted to the throne, Li Chengqi became the Crown Prince and was also conferred the title of Prince of the Frontier.

When Li Dan ascended the throne for the second time, the first question he faced was who to appoint as the Crown Prince. Li Chengqi was very astute. He knew that his father’s accession to the throne was due to his younger brother Li Longji’s defeat of the Wei family group, so he stubbornly refused and firmly recommended Li Longji as the Crown Prince.
Li Longji is not suitable either. He keeps saying that you are the queen and the elder brother, so you are the most suitable. Li Chengqi cried bitterly, as if being the Crown Prince would take his life. After crying for several days, Li Dan finally said that what you said made sense, and that the Crown Prince should let those who have made great contributions take over.
They were reasoning like this, and Li Longji couldn’t help but talk about etiquette. It took him a long time to agree. The father and son all have excellent acting skills, and Oscar owes them a little gold medal.
This grand play of fatherly love, filial piety, and deep brotherhood deeply moved the ministers, who cooperated very well and were widely praised. So the people all know how harmonious the royal family is, and it is impossible for such a fratricidal incident to occur in the previous dynasties, which has been widely circulated among the people.
With the confirmation of the crown prince’s position, Li Chengqi finally breathed a sigh of relief and saved his life. Since then, he has been self disciplined and self reflective, and passed away at the age of 63 with the posthumous title of “Emperor Rang”, which is very straightforward.
Li Longji has always been the most outstanding among Li Dan’s six sons. He has been brave, courageous, and versatile since childhood. Wu Zetian and Princess Taiping both like him very much. Even after being imprisoned in the palace for seven years, I did not succumb to despair, but developed a cautious and confident personality that allows me to take immediate action.
Among her nephews, Princess Taiping admires him the most. So it was only after the death of Emperor Zhongzong Li Xian and the reign of Empress Wei and her followers that the two nephews united to fight back, known as the “Tang Long Coup” in history.
However, after Li Dan succeeded to the throne, he trusted Princess Taiping very much and liked to ask for her opinion on anything, which damaged the rights and interests of Crown Prince Li Longji. The conflict between his aunt and nephew became increasingly intense, and Li Dan was caught between the two, unable to manage his sister or son, so he decided to abdicate.
After ascending to the throne, Li Longji gained greater power and, through a series of arrangements, executed Princess Taiping. His kingdom was now considered stable. With the assistance of wise officials, he created the “prosperous era of Kaiyuan” and can be called a generation of wise rulers.
