In fact, it should be reversed, with the sky above and the earth below, (picture) the left is yang, which is east, (picture) the right is yin, which is west, (this is not based on human left and right, Instead, it is based on the "picture" that people see, the left and right of "objects"), the left side of the pattern is "Yang Shi", the Yang Shi "fish" is head up, rising from the east against the clock, and the left side is the male Yang, rising. The right side of the pattern is "Yin deficiency", and the Yin "fish" is head down, also going against the clock, sinking from the west. This is the same as the sun rising and setting. And together with "left green dragon", "right white tiger", left solid and right virtual, they are in line with the spiritual context of "Yidao". Nowadays, people do not distinguish between left and right, because people mistakenly take "I" as the center, instead of taking the "object" scene being "discussed" as the subject, and the left and right of the "object" as the center.
