When a six-pointed star is shot, first determine which house it belongs to. The method is as follows: from the initial yang to yin, yin to yang, until it becomes consistent from top to bottom, which palace is consistent with the pure hexagrams. However, it should be noted that if it is changed to the fifth, it is not pure and cannot be changed to the sixth. When it becomes a pure hexagram, it is the world hexagram, and every two hexagrams should be hexagrams; The sixth trick of pure divination is important to the world, and the next trick is all changed back to the third trick.
When the world is determined, it is a dynamic divination, depending on how the divination started. If the hexagram is easy to start from plum blossom, it means that the above hexagram and the following hexagram are added together, and sometimes other differential information numbers will be added when the year, month and day are added. The sum above is divided by six, and the remainder is the dynamic hexagram (bottom-up). If it is made of a treasure of Yi Long, the three-character or three-sided hexagrams are moving. Without them, there is no movement, which is called six hexagrams.
