Two ancestral Feng Shui books, a trip to Huang Shigong and a question and answer in Liu Bowen, please understand and estimate their value.

If the price of cultural relics is estimated in thousands, the price of 10 thousand yuan may not be very large. If it is handwritten, the price may be slightly higher.

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

So this thing is not easy to evaluate.

Since it is ancestral, why haven't you learned such skills? But post it and ask the price?

This kind of thing was a secret before it was put.
