Rooftop Earth (wū shàng tǔ) is the NaYin of BingXu and DingHai. City-Wall Earth guards a city; Rooftop Earth guards a household: fired into tile, mixed into mortar, laid over the ridgepole — from then on, whatever the sky drops never reaches the people underneath. Xu and Hai close the year, when all things return home, and this earth too has walked the whole earthen road: soil of the field, soil of the road, and at last up onto the roof — the most tangible stroke in the word "home."

The classical imagery

On the earth of BingXu and DingHai, the San Ming Tong Hui says:

“The qi has become a storehouse of things and its affairs are brought to fine completion — yin and yang traversed in full, its station settled between them: hence it is called Rooftop Earth.”

— Wan Minying (Ming dynasty), San Ming Tong Hui, vol. 1, “On NaYin Imagery”

"A storehouse of things, brought to fine completion" — a storehouse is where things are kept; fine completion means the work is rounded and whole. With the year running out, Earth's mission here reaches its close: it grows nothing further, and answers only for keeping safe everything already gained.

Traditional reading of the temperament

Tradition reads a Rooftop Earth life as a born roof: family, friends, colleagues — whoever stands near feels settled, knowing troubles will be caught and rain will be kept off. Homemaking is close to instinct for this life, which values living well above everything else; its knack for running a family and holding onto what has been built usually outstrips its peers.

The old texts leave two pieces of advice. A tile fixed to the ridge cracks when pried loose — for this life the cost of changing environments runs higher than for most, and great relocations deserve second thoughts. And a roof faces the sky all year, meeting every rain and snowfall first — after long sheltering of others, remember that you too need somewhere to get out of the rain. On men and women, the old line — the male raises the family estate, the female excels as helpmate — is talk from under old eaves; take the gist and leave the rest.

Relations with other NaYin

In folk NaYin lore, Rooftop Earth wants Fire to bake its tiles and Wood to raise its pillars: Fire in the Furnace hardens the tile, while Plainland Wood and Great Forest Wood supply beam and post — together, the full crew of a house. What it fears is Sky-River Water, the downpour pressing on the ridge. On matters of the roof, though, the people living beneath it have the final say — recite every verse there is, and none is worth as much as the plain words "a household at peace."

FAQ

What kind of earth is Rooftop Earth?
In the old way of building, clay was fired into tiles and mud plastered over the ridge — Rooftop Earth is that layer of work overhead. The San Ming Tong Hui says its "qi has become a storehouse of things, its affairs brought to fine completion": Earth arriving at Xu and Hai has rounded everything off, turning into the roof that keeps wind and rain off a whole family.
Was someone born in 2006 a Rooftop Earth life?
Yes — anyone born in 2006 (BingXu) has Rooftop Earth as the NaYin of the year pillar. The year boundary follows LiChun (start of spring): those born before LiChun on February 4, 2006 belong to the previous year YiYou, whose NaYin is Spring Water.
What is the weak point of a Rooftop Earth life?
The old books put it vividly: a tile is secure in its fixed place on the roof and breaks when moved — this life clings to home and to the familiar, and loses its bearings away from its own "roof." And having spent years keeping the rain off others, its own grievances often have nowhere to go. This is associative imagery; use it as a mirror for self-reflection and nothing more.
