Structural Analysis, Meaning, and Philosophical Inquiry of the Hexagram Huotian Dayou (Fire Over Heaven)
This article systematically investigates the fourteenth hexagram of the *I Ching*, *Huotian Dayou*, analyzing its structure (Li over Qian), delineating the rich connotations of 'Great Possession,' and interpreting its principle of 'One Softness in Supremacy Responded to by Five Yangs' through the lens of Pre-Qin texts, thereby revealing its profound significance in ancient political philosophy.
II. The Line Count of the Da You Hexagram
The total number of Yang lines in Da You: Initial Nine (9), Nine Two (9), Nine Three (9), Nine Four (9), Upper Nine (9)—five nines. The Yin line is Six Five (6). The sum is $5 \times 9 + 6 = 51$.
The Xi Ci Zhuan, Part I, states: "The Great Elaboration number is fifty, and its application is forty-nine" (大衍之数五十，其用四十有九). The Great Elaboration number fifty is close to the total line count of 51 for Da You; this might not be coincidental.
