Years later, with the encouragement of the public, Feng Shui-loving friends, and clients, the Zǐ Wēi Dòu Shù book was re-published with a revised material for a more complete content and has finally been published in an English version. "This book is organized like an encyclopedia so that readers can look up the interpretations directly after knowing their 明盤 Míng Pán (Map of Life). In order to keep the information up-to-date, this book has been revised with the most obvious addition being the interpretations and meanings of the main stars which changes due to the 4 四化曜 Sì Huà Yào in each star.
