Upbeat Vietnamese folk feel, brisk tempo in 2/4 with bright đàn cò lead answering lively hand-played drums. Male vocals, call-and-response group backing in the chorus. Mix of claps, light shakers, and stomps to mimic festival energy; subtle mouth percussion to drive the rhythm. Energy starts playful and warm, peaks in a big communal singalong hook, then eases out on a smiling, nostalgic tag.
