The "Tai Chi Diagram" of the Yin-Yang Fish was once called the "Innate Natural River Diagram."
In Blue Star, it could be said to be known to every household, and even recognized worldwide. It was used not only for architectural decorations but also as national flags and military emblems by countless countries and their armies.
"Tai Chi" represents the state of the universe before the opening of the heavens and earth, where the chaos has not yet been divided into yin and yang.
A simple pattern, yet it elucidates the process of the universe from the undifferentiated state to Tai Chi, and ultimately the creation of all beings, embodying the highest virtues of the Way and the natural laws.
Scholars from various countries found it hard to believe that this knowledge could have been researched by the ancients of Xia Country.
Lately, pottery from the Neolithic era had been unearthed, bearing patterns similar to that of the Yin-Yang Fish.
