Duoxie Qiaokuo

Duoxie Qiaokuo (多谢巧蔻, literally Thanks a Lot Carmen) is a patriotic song and the de facto anthem of Mainland Aschsenland which vaguely 'thanks' Carmen for leading the nation into its prosperity. It is in Chinese.

Info
Melodically it resembles a religious chamber music and it sounds solemn. Despite this though, the lyrics are about thanking Carmen for being the architect for new Aschsenland and the establisher of the URPBMSC. Although it doesn't actually reference Aschsenland or the Union anywhere in the hymn, it does reference her uniting all of the Union's territories under a single union, which has been done exactly the same way by preceding leaders, notably Matt himself, Praescribo, Star Butterfly and Isabelle. In fact, Carmen being the establisher of URPBMSC is very analogous to Isabelle being the establisher of the former Caelite Union, which constitutes 75% of the current territory of the Union.

Lyrics
The lyrics are that of a typical patriotic song written for someone's cult of personality (cf. Tangsini Ŏpsŭmyŏn Jogukto Ŏpta); in this case, it's for Carmen.

Trivia

 * Despite it being directed to her, Carmen also sings this song, basically thanking herself in the third person. This is evidenced in A Terrible Fortress wherein when the patriotic song played when the main telly station signed off she started singing it on a whim.
 * She might be the only leader in the world to sing something dedicated to themselves.
