Is this book really endorsed? What's the situation inside?

In fact, there should be this book.

Push-back maps can be found on the Internet.

But not comprehensive

Maybe it is really hidden in the snow.

Or have long since disappeared into history.

No one can say that what he knows or sees is the real tuibei diagram.

However, I was lucky enough to see the plagiarized version, but it was only a quick glance (actually I couldn't understand it)

Occasionally, I have read "Lu Ban Shu" (copy it after you finish it)

The content is really mysterious, and its authenticity cannot be verified.

It is said that what is in the study book depends on whether the grandfathers give it or not.

There should be some miscellaneous preparations.

What else is there? What else is there?

It seems to be beside the point.

Get down to business

The tuibei diagram is true. But the picture above is obscure and difficult to understand, which is many times more difficult than reasoning.

Now you can search the cracked pushback map on the Internet.

But please tell yourself whether it is true or not.
