In AD 653, at the beginning of the fourth year of Yonghui, it was the fifth year after Gaozong Li Zhi succeeded to the throne. The Tang Dynasty was peaceful and prosperous. In order to fulfill the late emperor's last wish, Emperor Gaozong of the Tang Dynasty built two square and round altars at the Guangming Peak and the foot of Mount Tai. He wanted to lead all the civil and military officials to conduct the first Zen ceremony at the founding of the country, in order to establish the imperial prestige, take back the government that had been controlled by Changsun Wuji and Chu Suiliang, and stabilize the country. For a time, the whole country was celebrating.
