What works did Li have in Tang Dynasty?

Push back the picture. Written by astrologers Li and Yuan Tiangang. Li calculated with Zhouyi Bagua. Unexpectedly, he was addicted and out of control. He actually calculated the fate of China for more than two thousand years after the Tang Dynasty, until Yuan Tiangang gave him a push and said, "Let's go back and rest." Therefore, this wonderful prophecy book was named "TuiBei Map". There are 60 images in TuiBei Tu * *, and each image is accompanied by a prophecy and a poem "Ode to Yue", which predicts the great events in the history of China from the early years of the Tang Dynasty to the next 2000 years.

Linde calendar. Li compiled a new calendar in the second year of Linde (665) based on his years of research and long-term observation on astronomical calendars. On the recommendation of Nangong, Taishiling and Kong, Tang Gaozong sent a letter named "Lindley".

History of the Five Dynasties. During the Zhenguan period of the Tang Dynasty, after the compilation of historical books of Liang, Chen, Beiqi, Zhou and Sui dynasties, there was no "chronicle". In the fifteenth year of Zhenguan, Yu Zhining and Li were ordered to compile Records of the Five Dynasties, which lasted fifteen years and was completed in the first year of Qing Dynasty (656).

Yi Sizhan (10) is an important book of astrology by Li. The preface of the first volume of Yi Sizhan was written by Li, which explained his intention to write this book and his compiling thought.
