Secret

Successful people often say: "The secret of heaven must not be leaked." Then, they will put the motto of heaven's secret that makes them enlightened and swim against the current on the shelf, and will never show it to others easily. Because those secrets that seem obscure and mysterious at first are actually too down-to-earth and feasible. Something that everyone can practice must naturally be packaged repeatedly so that others cannot easily covet it. A phoenix doesn't mind a few more crows standing on a branch, but it will certainly mind an extra phoenix standing next to it. In this book, we have broken these secrets apart and put them in plain sight. We will never be vague or secretive, just so that every reader can benefit from reading the book.
