The issue of differences in calendars has long been successfully resolved by the author of scientific discovery of the Catalog of Human Population, research supervisor of our laboratory Andrey Davydov when he created the technology for decryption of Shan Hai Jing, which turned out to be the Catalog of Human Population. This technology was verified through Russian scientific institutions back in the 90s of the last century. As it is known, verification of scientific research is the proof that a scientific theory or technology work.
Not to mention that the Catalog of Human Population is being used in practice for over 20 years (from the date of verification), and has been used extensively by government structures of Russian Federation, such as the Federal Security Service, the State Duma, etc. More on this can be found in the following books: Ideology of Religions by A. Davydov and O. Skorbatyuk and Shan Hai Jing–A Book Covered With Blood. The Story Of Developers Of The Catalog Of Human Population. by K. Bazilevsky. It is not difficult to understand that structures at such level do not use technologies that do not work. By the way, as you are planning to place an order, probably to some degree you have already tested out the possibilities of our product using free demos presented on our website, have you not?
