Tang Xuanzong personally gave his son a yellow robe and a title, so why was he driven into the Tai Chi Palace?

Tang Xuanzong personally wore a yellow robe and added a title to his son. However, after Tang Xuanzong became the Supreme Emperor, he could see the lives of the people outside and the officials coming and going through the windows in Xingqing Palace where he lived. Therefore, Tang Xuanzong He often communicated with them. For this reason, Tang Suzong was deceived by Li Fuguo and said that Tang Xuanzong was buying people's hearts and planning to restore. Tang Suzong was worried that his throne would allow Li Fuguo to send Tang Xuanzong to Taiji Palace for imprisonment.

On his way out of Chang'an after the An-Shi Rebellion, Prince Li Heng launched a coup in Maweiyi, forcing Emperor Xuanzong of the Tang Dynasty to become the Supreme Emperor and Li Heng to become Suzong of the Tang Dynasty. After Chang'an was recovered, in order for Tang Suzong to gain people's love, Tang Xuanzong personally put on a yellow robe for Tang Suzong, and was grateful to Tang Suzong for making a down payment to Chang'an so that he could retire in Chang'an.

Since then, Tang Suzong and Tang Xuanzong have been living together peacefully, just like Tang Xuanzong took the initiative to abdicate the throne, until Tang Xuanzong, because he missed Yang Guifei deeply, proposed to take back Yang Guifei's body to hold a grand funeral for her. And buried in the Tang Dynasty Cemetery. However, this proposal was opposed by the ministers, because bringing back Concubine Yang would prove that the Maweiyi coup was a rebellion by Emperor Suzong of the Tang Dynasty and other soldiers, which would be chilling. Although Tang Suzong neither agreed nor objected to this, his relationship with Tang Xuanzong gradually deteriorated since then.

After the relationship between Tang Xuanzong and Tang Suzong became good, he rarely appeared in public. However, Xingqinggong, where he lived, faced the street outside. Tang Xuanzong often invited some people on the street to drink and have dinner together. After getting familiar with it, people who came and went often said "Long live" to Tang Xuanzong. This matter spread to Emperor Suzong of the Tang Dynasty, which made him feel very uncomfortable. He felt that Emperor Xuanzong was trying to win over people's hearts. After that, Emperor Xuanzong also hosted a banquet for General Guo Ying and others in Xingqing Palace. Many local officials also came to see Emperor Xuanzong when they came to report on their work. , which made Tang Suzong feel that his original throne was obtained through coercion, so he was always on tenterhooks and feared Tang Xuanzong's restoration. But Tang Xuanzong was already 76 years old at that time, so what else could he do.

Seeing this, Li Fuguo was like Tang Suzong suggesting that the best way to prevent Xuanzong from seeing others was to let Tang Xuanzong live in Taiji Palace and confine him there. He would not be able to contact other people this time. Li Fuguo's words played into the hands of Suzong of the Tang Dynasty, and Xuanzong of the Tang Dynasty was asked to enter the Tai Chi Palace until his death.
