易經-裝卦

"Tai Chi is easy to have, two yis produce two yis, two yis produce four images, and four images produce gossip."

The eight hexagrams are arranged and combined to produce sixty-four hexagrams. The "gua" is a unique tool for expressing thinking in the Book of Changes.
"Picture Gua" is counted from bottom to top and is called the first line, the second line, the third line, the fourth line, the fifth line, and the upper line in order.
Together with the lunar calendar, solar terms and movement lines form a complete hexagram image. Because of its unique changes, a slight negligence will completely invalidate the incorrect interpretation of the hexagrams.

The I Ching-Zhuang Gua APP is now easy to use for fellow practitioners. I hope it will be helpful. It only has the function of sorting out hexagrams but not solving hexagrams.
