Tai-Ji is a very important concept when we study ZWDS. ZWDS Chart is a Tai-Ji, Self Palace is a Tai-Ji, Sibling Palace is a Tai-Ji, “Self Palace + Sibling Palace” is a Tai-Ji — when we want to find out the relationship with our brothers & sisters.
Stock Market is a Tai-Ji as well. Yang in here means share price up and Yin in here means share price down. When we found the relationship and balance of Yin-Yang of the stock market, plus the ZWDS technique regarding personal circumstance, particular industry and particular stocks, we will have a comfortable life style all the time.
