Master S. R. Chang was born in the Republic of China and later immigrated to the United States of America. He developed keen interests in ancient Chinese predictive arts and systems at an early age. Over the last twenty-plus years, he has passionately investigated and successfully decoded various ancient Chinese predictive systems. During his decades-long quest to understand the ancient Chinese predictive arts and systems, he was most fortunate to be chosen and allowed to learn some of the most closely guarded systems. Fulfilling a part of a vow made years ago, he is now selectively introducing some aspects of the ancient Chinese predictive arts and systems to a wider audience.
