Fortune-telling mystery novel

I have been watching the mysterious case in the spring of the Northern Song Dynasty recently. The protagonist is a fortune teller, a rich young master and an ancient theorist. I have read many articles on reasoning. This article is very meaningful, and the case is well described, the tactics are good, and the characters are very distinctive! And not boring. The only drawback is that there is only one book, The Forbidden City, and the second one seems to be serialized.

Really super nice.

I don't know what you want, but I prefer the old one. You can ask me about the detailed categories.

Many abroad. I like Japanese and Keigo Higashino. The endings of all his books are unexpected, reasonable and thought-provoking. I especially like his Yukawa studies.

I still like Sherlock Holmes best in the west. If you are interested, I like Poe's, too.

There are many in China. I don't know which one you want.

Di Gong An is the work of Gao Luopei, a Dutch writer, and the originator of De Renjie. That's good.

Love reasoning, looking for Mo Ding.

What kind do you want? There are many kinds of reasoning.
