ใชใใชใใฎ็ณง is a poetic phrase meaning โthe little sustenance one hasโ or โoneโs meager provisions.โ ใชใใชใ describes something scarce or nearly all that remains, while ็ณง means nourishment, provisions, or figuratively the support needed to keep going.
In the song, the travelers clutch their bare essentials and run forward toward the future. This vivid expression gives the journey a sense of hardship, determination, and hope.
"D.C." by m.o.v.e is a sunrise song. It opens with the sun climbing as if it were tracing an outline, "่ผช้ญใๆใใใใซๆใ้ฝใ" (the sun rising as if drawing an outline), warming the night but also making new shadows. Then comes the sharp question at its centre: "ๅคฑใใใจใงใใๆฐใฅใใชใ" (we only notice by losing), so what do we have to do to protect what matters? It's a big question for a song this upbeat, and I like that it doesn't pretend to have a neat answer.
The answer it does give is a little extreme. "่จ่ใฏๆจใฆใฆใใใ" (I can throw away words) and "่บซไฝใใใฎ็ผใใชใใใฆใใใ" (I can even lose this body and these eyes), as long as a heart that can hold "ใญใ" (you) is left. After that the song keeps returning to fabric: the future is "็ด็ฝใฎใทใซใฏ" (pure white silk), and "ไปๆฅใใคใชใใง ๆชๆฅใ็นใไธใใฆ" (linking today, weaving the future). There's a nice detail in "ไปๅคใ XII ใ้ใใ้ " (tonight too, around the time past XII): those are Roman numerals, a clock face striking midnight.
Worth learning: "ใชใใชใใฎ็ณง" means "the little food we've got", the bare scraps you run with, and "ใใๅบใใใ " (come on, step out) is a handy casual push to get someone moving. By the end, "ๅธๆใ็พๅฎใซๅคใใ" (hope turns into reality), and you can hear it getting closer.
