How did Yuan Tiangang and Li die in history? Have they become immortals?

There were two goddesses in the Tang Dynasty, one named Yuan Tiangang and the other named Li. In the Tang Dynasty, they were two star figures, from civilians to emperors, and no one worshipped them crazily, so they were called old immortals. Later generations even worshipped them because of their magical prophecy in the book TuiTui. Since Yuan Tiangang and Li are called old immortals, how did they die in the end? Have they become immortals?

Yuan Tiangang, a metaphysicist at the end of Sui Dynasty and the beginning of Tang Dynasty, was best at physiognomy. Historically, he met Cen Wenben, Fang and other leaders of the Tang Dynasty and made various predictions. The most famous place is that she met Wu Zetian, who was still a baby, and thought that she would become the son of heaven in the future. Yuan Tiangang was such a genius that his appearance became a celebrity, and he was summoned by Emperor Taizong and became the brain trust of Li Shimin. From then on, Yuan Tiangang not only didn't have to set up a stall to tell fortune, but also told fortune to senior officials, all kinds of waves, all kinds of hi, old immortals, and started to do it if they didn't agree.

Later, after Tang Gaozong ascended the throne, although Yuan Tiangang was also highly valued by the new emperor, he predicted that it would be a catastrophe to stay with the emperor. As a result, he excused himself to the emperor and the emperor entrusted Huojing County to return to Shu County. He died in the office soon after he came back. It has been said on the Internet that after his death, his tomb has not been excavated for thousands of years due to clever design. In fact, Yuan Tiangang was buried in Baihe Mountain in Qionglai after his death. Although the tomb has been stolen and destroyed, the remains still exist.

Li, a native of Qishan, Baoji, Shaanxi, was an astronomer, mathematician and Yi-ology scholar in the Tang Dynasty. He is a child prodigy, proficient in astronomy, calendar, Yin and Yang and Taoism. Later, he joined the army in Li Shimin, revised the calendar, changed the armillary sphere, and wrote books on astronomy and calendar. The most famous is that he and Yuan Tiangang co-wrote "TuiBei".

In the first year of Xianheng (670), Li died of illness at the age of 68. Tang Gaozong Li Zhi won another prize? Chasing Zhao? After Li, for? Taishiling? . After Li's death, he was buried in Lijiadao Village, a town about 60 miles east of Qishan County, and his grave did not escape the fate of being stolen.

In a word, Yuan Tiangang and Li, two great men, died in the end, which is a good ending. It's just that they are called old immortals, and legends can predict the future, but in the end, their graves have also been dug, which is a bit disappointing!
