Why can't I buy eight-character books?

Remember never to read the first fake book of the word "Tian Tian Mu", which is against reason. Although it is sometimes accurate (the book adopts the method of changing from negative to positive, that is, the mode of adding mistakes and changing pairs), although the result is correct, all the theories in the process are wrong, and after reading it, people will be embarrassed to be incompatible with other numerology books. This is a terrible place, which makes you addicted to it and unable to improve with other books with correct theories.
