What is Tianbao calendar?

Tianbao calendar is the year number of Li Longji, Emperor Xuanzong of the Tang Dynasty (from January 742 to July 756), with a total of 15 years. In the first month of the third year, Tianchaobao changed "year" to "load".

In November of the 14th year of Tianbao (755), Fanyang and other three towns made An Lushan unite with Shi Siming to launch a rebellion in Fanyang in the name of killing Yang, which was called "An Shi Rebellion" in history. Since then, the Tang empire has turned from prosperity to decline, which is a major historical turning point.
