According to statistics by Nguyễn Thị Lan, Tự Đức thánh chế tự học giải nghĩa ca holds the largest collection of Chinese characters that are annotated with chữ Nôm.

[9] Hà Đăng Việt states that the Nôm in the book mainly uses three methods of creating characters, giả tá 假借 (phonetic loan), hình thanh 形聲 (phonosemantic compounding), and hội ý 會意 (compound ideographs).
