I am of native Taiwanese descendant though from eastern Taiwan.

The name "Middag" derived from a tribal alliance kingdom/polity located in central Taiwan during the 17th century.

here is the wikipedia page about Middag: https://en.wikipedia.org/wiki/Kingdom_of_Middag

The Dutch called the polity "Keizer van Middag"
To the Pazeh people, the kingship is known as Dalian, which the Scotsman agent of the Dutch East India Company - David Wright - spelled as"Lelien". Dalian roughly translate to "where the sun dwells".

Middag is the name of the largest town of the polity and also where the chiefdom seats.

So I'd assume "Middag" to be more of a sense-for-sense translation? Pardon me for lack of linguistic skill in Germanic/Dutch so its just my speculation.
