The Ruler's Guide: China’s Greatest Emperor and His Timeless Secrets of Success, by Chinghua Tang is a book that examines the discussions and discourse of the second Tang Emperor Taizong of Tang, and his court advisors and generals. The discussions are of the style of Confucian lectures, with small blurbs containing advice, guidance, principles and ethical statements all geared toward the modern business or political leader or those interested in management styles. The book is adequate at what it does, and is a short and quick read, all to its benefit. The lessons to be conveyed in the book are geared toward inner control and disciple, engaging and empowering subordinates, dealing with conflict, preparing for battle, and taking criticism - all common ideals found in many modern business books. This book is slightly innovative in its approach, and reminds me of similar books I have read modernizing Marcus Aurelius' Meditations. Both books contain the collective writings and wisdom from autocratic leaders in the past, and both seek to take this advice and present it to a modern business focused readership.
This book did have some glaring flaws. The sourcing was atrocious - this would have been an excellent book to give the reader a comprehensive source list of Chinese documents and literature to read and discover. Instead the book contains no sourcing at all. I also took issue on a few of the topics offered. For example, Tang has added a section that is anti-"big government" - an oddity in this book for sure. For one, Emperor Taizong was an autocratic leader in a nation that is famed for its expansive and historically professional bureaucracy. Putting a Republican and wholly American viewpoint such as that in The Ruler's Guide felt inappropriate and out of place - it certainly offers no clear advice besides a bit of back patting for Republican business leaders. Other examples of inexplicable and useless topics are present in the book, and felt like a waste of time and space in my opinion.
Even so, this is an enjoyable book. It is slightly innovative in that it covers a famous historical figure largely unknown to the average Western reader. It is also an interesting way to examine history to gain insight and personal guidance through the writings of those who have succeeded in history. Problems with sourcing and scope creep are present, but other than that, this quick and easy read is certainly enjoyable for those who enjoy business/leadership style books, and those with a passing interest in Chinese history.
