Two ancestral geomantic books, Huang Shigong's Trip, and Liu Bowen's Questions and Answers, please understand and estimate their values.

if the price of cultural relics is estimated in thousands, the price of 1, yuan may not be very large. If it is handwritten, the price may be slightly higher.

However, it may be priceless in the eyes of Kanyu scholars (the key lies in the evaluation of content value, and if it is unique, original and has been interpreted in past dynasties, its value will be immeasurable)

So it is difficult to evaluate this thing

Since it has been passed down from generation to generation, why didn't you learn such skills? But post it and ask the price?

this kind of thing was a secret book before it was put.
