The Old Bridge with Rotten Wood

古橋朽木

Original (Kanbun)

古橋外見尚為固 / 内木朽爛踏即崩 / 表象不可尽信頼 / 試而不入方為知

Literal Translation

The old bridge, from outside, still appears solid / Inner wood rotted — step on it, and it collapses / Outer appearance cannot be fully trusted / Testing without crossing is itself knowing

Modern Reading

Something that looks reliable to you is not, in fact, reliable — and the appearance of reliability is itself the trap. A relationship that seems stable. A job that seems secure. A plan that seems solid. The misfortune is in committing your full weight before testing whether the structure can bear it. **Step lightly. Test before crossing. The bridge has not been examined in a long time.**

Interpretation

Overall

Misfortune from misplaced trust in outer form. Something you have been treating as reliable has had its actual condition unexamined for too long. Verify before further commitment.

Love

A relationship that 'is fine' may be hollow inside. Have the actual conversation; do not commit further weight to untested ground.

Career

A job, contract, or commitment that seems secure should be examined for actual conditions — financials, leadership, viability. Do not assume because you assumed last year.

Health

A practice you 'always do' may not actually be working. Reassess.

Wish

Cannot be granted on the basis of your current assumptions about the situation. Verify; then ask.

Travel

Inauspicious for assumptions about familiar routes, vendors, or accommodations. Verify current conditions.

Lost Item

Was lost because of misplaced trust in the apparent secure place.

Guidance

When this sign is drawn, examine where you are conflating familiarity with reliability. Things you have used or trusted for years are not exempt from current verification. **The bridge is old. Test it before crossing.**

Cultural Anchor

The deceptive old bridge (古橋朽木, kokyō-kyūboku) draws from classical Japanese travel literature, where bridge maintenance was a real and recurring concern. The principle of distinguishing surface from substance (表裏, hyōri) appears throughout Japanese strategic thought, including Miyamoto Musashi's Book of Five Rings (1645). The Ganzan Daishi tradition uses this image for misfortune from unverified assumptions about reliability — what classical commentators called 過信の凶 (kashin no kyō), 'the misfortune of overtrust.'
