When humans first looked up at the starry sky and imagined the twinkling stars as heroes and mythical beasts, the culture of constellations planted the seeds of curiosity. From the ancient Egyptian priests observing Sirius to predict the flooding of the Nile, to modern urbanites browsing their daily fortunes in the morning, constellations have always used mysterious symbol systems to interpret the unknowns of life for us. This book will break the perception that "constellations are just for entertainment" and build a complete system from the origin of constellations to workplace, emotional, and health applications with astronomical background, psychological theory, and statistical analysis. Whether you want to understand your own personality through constellations or seek reference for life decisions, you can find guidance with both cultural depth and practical value in this book.
