How about Kaiyuan Zhan Jing?

The full name of this book is Tang Kaiyuan Zhan Jing, and the author is Qu Tansta (originally from India, whose predecessor moved to China from India). This book has a volume of *** 120, which preserves a large number of astronomical calendar materials and weft books before the Tang Dynasty, and also introduces the basic data of 16 calendar, such as chronology and chapter rate. This book is based on astrology. Therefore, in all kinds of taboos, it has been hidden by the government and basically not circulated among the people. So this book was rarely circulated in the Tang and Song Dynasties. Until the forty-fourth year of Wanli in Ming Dynasty (16 16), a scholar named Cheng Mingshan in Shexian County, Anhui Province, found a manuscript in the belly of the ancient Buddha statue because he gave it gold. Today, the carved towel box of Hengdetang was widely circulated in Daoguang period. Thirdly, the astronomical value of this book is greater than the divination value. In addition, those who have no knowledge of astronomy seem to be struggling.
