Da Nang 峴港 Dragon Bridge Vietnam  

Note 234 Rainbow and Dragon in Vietnam 

Common features shared between many indigenous groups with regards to Rainbow include - 

Rainbow and Bridge

Indigenous word for Rainbow (for what I read in 1935 report and others online) all developed from Chinese word 虹 - an arch-backed two-headed worm 虫. Perhaps with one exception (again - for what I read) - Saisiyat.

Utux 靈- Ancestral Spirits

Rainbow connection with ancestral spirits is ubiquitous in indigenous cultures.

Examples - 

Kachirai 加芝來社 Paiwan - Rainbow

qolivag - 虹 - Rainbow

Also notice qolo - head 首 (Proto-Malayo-Polynesian)

Saisiyat Bridge and Rainbow 

乘涼 （sit in the shade. enjoy the cool)

Ta'ai 大隘 Tribe. The only matching word to Bridge is 納涼 (relax in a cool place/in the shade)

Ta'ai 大隘 Tribe ta'ai tale - 
 Bridge 橋 (虹) 納涼.
Connection to Spirits 神

I am surprised to find Saisiyat word for  bridge appears borrowed from Japanese 納涼 . At least I find no matching words that make sense or find other terms that can explain. And it certainly match the tale illustrated by ZALAN. Interesting, isn't it.
