In our daily lives, the practice of flipping through a dictionary and randomly selecting a few words to make a name cannot be called "naming science." In the true sense, "naming science" is a kind of numerology that contains the concepts of five-frame mathematics, yin and yang, and five elements. It is a branch developed from the "Book of Changes", China's oldest and most profound philosophical work. Thanks to the charm of the "Book of Changes" itself, the science of naming can be said to be profound and long-standing. Moreover, its life experience is more twists and turns and more legendary than the spread of the Book of Changes itself.
