䷉ 履 Lv (Treading) is number 10 in the King Wen sequence and number 60 in the binary/Fu Xi sequence. Its outer (upper) trigram is 乾 Qian (Heaven); its inner (lower) trigram is 兑 Dui (Lake). Jing Fang's eight palaces place it in the Gen palace (Earth), as the Fifth generation, seated on line 5 with the responding line at 2. Its na jia lines are Ding Si, Ding Mao, Ding Chou, Ren Wu, Ren Shen, Ren Xu; the six relations follow from the palace element and each branch element. Cuo, zong, hu and the other seven hexagrams of the palace are all derived from the two trigrams.

Na jia pins each line to one stem-branch: Qian and Kun use different stems inside and outside (Qian takes 甲 then 壬, Kun takes 乙 then 癸), the other six trigrams keep one stem throughout; yang trigrams (Qian, Zhen, Kan, Gen) step forward through the branches and yin trigrams (Kun, Xun, Li, Dui) step backward. The six relations are then read off by comparing each branch element with the palace element: same = sibling, what I generate = offspring, what generates me = parent, what controls me = officer, what I control = wealth.

Six-relation count for this hexagram: Parent 2 · Sibling 2 · Offspring 1 · Wealth 0 · Officer 1
The six spirits (Azure Dragon, Vermilion Bird, Gouchen, Flying Serpent, White Tiger, Black Tortoise) are deliberately not listed here: they are assigned from the day stem of the day you consult, so they are a variable of that day, not a property of the hexagram. This site gives the rule, not the day.
All three are pure derivation: the cuo (opposite) hexagram flips all six lines, the zong (reversed) hexagram turns the figure upside down, and the hu (nuclear) hexagram takes lines 2-3-4 as its lower trigram and 3-4-5 as its upper. None of it touches na jia or the palaces, so each can be checked on its own.
| Cuo (all six lines flipped) | ䷎ 谦 Qian — every line the opposite of this one |
|---|---|
| Zong (turned upside down) | ䷈ 小畜 Xiao Xu — read this figure from the top down |
| Hu (nuclear) | ䷤ 家人 Jia Ren — lines 2-3-4 below, 3-4-5 above |
Jing Fang's eight palaces organise the 64 hexagrams as eight family trees of change: starting from the pure hexagram of the palace, flipping line 1, then 2, then 3, then 4, then 5 gives the first through fifth generations; flipping line 4 back from the fifth gives the wandering (you hun) hexagram, and flipping the inner three lines back gives the returning (gui hun) one. Each palace holds exactly eight, and the eight palaces tile all 64 with no overlap. This hexagram's place in that tree is marked.

Eight hexagrams share this upper trigram and eight share this lower one (this one is in both lists). Both groups are pure combinatorics — a quick way to see the same trigram in other settings.
Every na jia branch links back to this site's branch page, and every line's stem-branch links to its day-pillar page. That is the joint between this family and the ba zi layer: na jia runs on the same stem-branch system.
