	7-Fire Middle joint	(5)	3-Water Middle joint
Fingertip of thumb as internal trigram (self)	6-Thunder Root	1-Earth Root	2-Mountain Root

The method of memorizing the 64 hexagrams of the I Ching by associating them with the joints of the fingers on the left hand, with the thumb representing the internal trigram and the other fingers representing the external trigram. The table below shows the correspondence between the different joints of the fingers and the eight trigrams. By focusing on the meaning of each hexagram and the corresponding joint, it is easier to memorize the hexagrams and their names. (The table head represents the left thumb)
