How to remember the orientation map of sixty-four hexagrams?

To remember the orientation map of the sixty-four hexagrams, we must first remember the order of the eight diagrams: Cognac, Duier, Li San, Paul, Xunwu, Liu Kan, Genqi and Kunba. From the square diagram, from bottom to top, it is the order of gossip, and from right to left, it is also the order of gossip, so that when the square diagram of gossip is accumulated, the sixty-four hexagrams will be remembered without memorizing.

The chart is: the top is south or north, and Zuo Dong is in the west. Take the first row of "palaces" at the bottom of the chart and put them directly to the south, and then to the east, where one is two, three is three, and four is earthquake. On the other hand, Xunwu, Liu Kan, Genqi and Kumba are also arranged from due south. You don't have to remember the sixty-four hexagrams on the map of Fiona Fang.
