Qian · Heaven
天的圖象。出現在上卦代表主導、君位、父；出現在下卦代表內在剛健、潛力。讀到乾，立刻想：純粹的推動力在哪裡？
Image of Heaven. Above: leadership, ruler, father. Below: internal strength, latent power. When you see Qian, ask where the pure driving force is.

從上面任一組挑三個還沒讀過的卦，按如何讀象的六步去讀。 注意乾在不同位置的功能差異：它在上卦時的動作，和在下卦時的動作不一樣。
Pick three hexagrams from above you haven't read, and walk through the six-step reading. Notice how Qian's function shifts between upper and lower: same image, different role.
