'salt-water town'), alternatively spelled Yanshui, is a district in Tainan, Taiwan, which is famous for its notoriously dangerous fireworks festival.

The annual event commemorates a cholera epidemic more than a century ago, the fireworks symbolizing the exorcism of demons associated with the plague.

The deities of Heaven are able to inspect the land on the day of Lantern Festival by carrying the statue of Kuan Kung in palanquins and paraded around Yanshuei and letting off masses of firecrackers, and the epidemic soon receded.

The most important of Yanshuei's prominent fireworks are the so-called "bee hives", essentially multiple launchers of bottle rockets.

Local residents modify motorcycle helmets by riveting fire retardant material to create an aventail at the back and a flexible gorget at the front.
