Although there are some books on Chinese 36 strategems in the market, most writers did not apply the I Ching or Yi Ching (Book of Changes) in interpreting these tricks. Book of Changes (I Ching) is the most ancient and mysterious source of Chinese thoughts and wisdom, including Confucianism and Taoism. Even Sun Tsz and Traditional Chinese Medicine (TCM) were shaped by principles of I Ching. I hope readers always read this little book from time to time. When you have problems of any kind, read randomly. Perhaps it will give you insights and possible directions.
