In ancient times, which book was used to evaluate the tomb of the champion, and which book was used to sit in the position of eight characters with others?

In ancient times, Champion Tomb's book was specially judged, and the book of sitting with people in eight characters was the numerology classic "Five Elements".

The book "Five Elements" records a character named "Lu Zhuangyuan" ("Jiayin Wuxu Month on the Day of Wushen"), but no specific name is recorded. According to textual research, there were two top scholars named Lu in the Song Dynasty, one was famous and the other was born in 10 14, which happened to be the year of Jiayin, so eight characters should be recorded in the book.
