Kaigui Men (開鬼門): Why Every Taiwan Temple Rings Its Bell Today (Ghost Month Day 1)

If you’re in Taiwan today and you hear a temple bell strike at sunrise, that’s not routine. That’s Kaigui Men (開鬼門) — the “opening of the ghost gate” — the single most important ritual on the Taiwanese lunar calendar’s most superstitious month. Ghost Month 2026 officially begins at dawn today, August 13, and the whole island quietly shifts gears for the next four weeks.

What actually happens at dawn

Kaigui Men (literally “open the ghost door”) marks the first day of the lunar seventh month. Folk tradition says the gates of the underworld swing open, and the “good brothers” (好兄弟 hǎo xiōng dì — the polite Taiwanese euphemism for wandering ghosts) get a 30-day pass to visit the living world. The ceremony is meant to welcome them respectfully, not fearfully.

The epicenter is Laodagong Temple (老大公廟) in Keelung, where the ritual is a serious civic affair. The mayor, senior monks, and Taoist priests show up before sunrise. A special bronze bell is struck, incense fills the courtyard, and the ceremonial key is turned in a tall, red-and-gold gate on the temple grounds. Locals arrive with joss paper (see our joss paper explainer for what they’re burning and why).

Why Keelung is ground zero

This isn’t random. The Keelung ceremony traces back to 1855, after a violent feud between Zhangzhou and Quanzhou settler clans left over 100 dead. Both sides eventually buried the unclaimed dead in a shared tomb — the “Old Grandfathers’ Grave” — and pledged an annual peace ceremony. That agreement became the modern Ghost Month opening rite. It’s genuinely one of the oldest continuously-observed civic rituals in Taiwan, and Keelung’s Zhongyuan Festival is now UNESCO-recognized on Taiwan’s national intangible heritage list.

What locals will actually do today

• Bai baimen kou (拜門口) — the “front-door offering.” Households set up a small table on the sidewalk with fruit, snacks, and three sticks of incense to welcome the good brothers politely.
• Buy joss paper by the ream — 7-Eleven and family-run paper shops stock up specifically for this month.
• Skip the front seat of the taxi — that spot is left symbolically open for a ghost passenger.
• No whistling after dark — folk belief says it invites the good brothers to follow you home. (Yes, seriously — even secular young Taiwanese still don’t do this.)

The gate closes again at the end of the lunar seventh month with a mirror-image ceremony called Guagui Men (關鬼門). For the full picture of what’s off-limits between now and then, see our Ghost Month 2026 taboo guide.

The takeaway: Ghost Month isn’t spooky. It’s respectful. If you’re in Taiwan today, drop by any neighborhood temple after work — you’ll see families lighting incense, feeding the good brothers, and quietly keeping a 170-year-old promise alive.
