Yang Guifei was a well-known Tang Dynasty woman, and was Tang Xuanzong Li Longji's favorite concubine, so if the emperor liked it so much, why did Tang Xuanzong not make Yang Guifei empress? The author believes that there are three reasons.
First, Yang Guifei was originally Li Longji's daughter-in-law, and Li Fei's matter was already out of line. In order to establish a concubine, Li Longji also made some cover-ups for this matter before and after, such as deliberately concealing the adoption of Yang Guifei's uncle and so on. Really establishing an empress, Li Longji definitely has more things to do. If you really set up an empress, then Li Longji will be guilty of Chen's self-tiredness.
The nature of a concubine and a concubine is different. Li Shimin took in his sister-in-law Yang, who bore him a son. Therefore, he once wanted to establish Yang As the queen, but later this matter was dissuaded by Wei Zheng. It can be seen that the establishment of the harem and the collection of the harem are two things. Li Longji was still jealous of a little fame. Moreover, Li Zhi accepted his father's concubine Wu Meiniang and did not come up and wanted to set her up. Wu Zetian Fuzheng was still after she gave birth to a son for Li Zhi.
Second, the relationship between Yang Guifei and Li Longji did not reach the posthumous share. After Li Zhihui established Wu Zetian as his successor, in addition to Wu Zetian's favor, Wu Zetian also bore Li Zhi a son. Then, Li Zhi deliberately cut off the influence of Changsun Wuji and others in the dynasty, and the original Empress Wang was classified by him in the system of Changsun Wujie, plus Li Zhi was also the eldest son of Wu Zetian at that time, Li Hong, who was also quite interested in Wu Zetian, and had the heart to change the status of crown prince. Fuzheng Wu Zetian was necessary for Li Zhi.
Li Longji is quite fond of Yang Guifei, but Yang Guifei is childless, purely for personal love, and it is not too necessary for Chen Wei to be tired. The key point is that Li Longji did not plan to change the crown prince at that time, which was also a factor for Li Shimin to abandon the Li Yang clan, because Li Shimin did not consider the son of the Li Yang clan. To put it bluntly, a living empress was established, and this empress was not the birth mother of the prince, which was not to make the prince uncomfortable, but to leave hidden dangers.
Third, Yang Guifei was once released by Li Longji back to the Yang family by Li Longji because she had intimidated the emperor twice. It can be seen that Yang Guifei's personality also has a more real side. The last woman who dared to intimidate Li Longji was his original queen. Later, the queen was deposed. After that, Li Longji did not appoint a living person as an empress, and to a certain extent, the function of the empress may also have certain restrictions on the emperor. Although the emperor can abolish the queen, but after the abolition, in fact, it is also a troublesome thing to go through the formalities. Establishing an empress was originally a troublesome matter for Li Longji, which was equivalent to finding someone to restrict his own behavior.
Therefore, Li Long basically did not want to be an empress again.
