What do you mean, up, down and moving? Please let me know! Would you please make it clear?

A double divination consists of two single divinations, such as: the sky and fire are the same divination, the upper divination is heaven, and the lower divination is fire;

Shifting hexagrams is to get the old Yin or Lao Yang in divination, such as: Heaven and fire are the same hexagrams, the second hexagram is the old Yin, and the fifth hexagram is Lao Yang. Then, this divination becomes detached and dry: fire and heaven are great divinations.
