Today, I look at the picture below from time to time, especially the four words "Huang Shang Yuanji" to try to understand the meaning.

combined with the analysis of hexagram and the line text, the fifth line has two advantages and four shortcomings.
1. Advantages.
〔1〕From the perspective of hexagram, the five lines are in the middle.
〔2〕From the perspective of the yao, Kun is the earth with loess as its true color, and the yellow dress of the fifth line just follows the core color of the Kun hexagram.
2. Shortcomings.
〔1〕The fifth line is out of position: the Yin line is in the Yang position.
〔2〕The fifth and second lines have no correct response due to the same sex rejection.
〔3〕The fifth and fourth lines are incompatible due to the same sex rejection.
〔4〕The fifth and sixth lines are incompatible due to the same sex rejection.
During the Shang and Zhou period, clothes were separated, clothes were on the top and outside, while clothes were on the bottom and inside. The fifth line wearing yellow clothes is a low-key behavior, and it also represents being content with one's own integrity, so there is a saying of "Yuanji".

at the end:
This line reminds us: When you are in a noble position, you cannot be arrogant and do not go against the general environment, so as to ensure good luck.
