The venue of Le 'an Lantern Festival.

In the custom of Le 'an, because the bridge has the communication function of connecting the two sides of the strait, its symbolic meaning naturally extends to life etiquette in many folk customs. For example, in our daily spoken language, it is often called "matchmaking" to help men and women meet and intersect. As the bridge is the medium of interpersonal communication, it is of great significance in expressing the metaphor of men's and women's negotiations and related events.

Lean is a water town in Lingnan, with many bridges. People are convinced that every bridge has a bridge god, and the Lantern Festival is held under the bridge because the bridge has the function of praying for heirs.

There is also a story about Le 'an Bridge. An old man rested on a bridge, finished smoking a bag of cigarettes and knocked over the hookah on the bridge. He didn't want the bridge to suddenly shrink, and he himself fell into the river. So the bridge is a male root. As soon as the ashtray was hot, it shrank back. Here, the bridge is likened to male genitalia, and the worship of male genitalia is also an ancient reproductive worship.

When the parturient in Le 'an encounters dystocia, they often run to the bridge to burn incense for the parturient, pray for mercy and get rid of the bridge.
