The cover bears the title in Chinese with a Latin inscription: “Explicatio | orationis Angelicae | a P. Jacobo Rho S.J.”

The title page gives the title in four large characters. The verso of this folio bears the names of the censors: Long Huamin 龍華民 (Niccolò Longobardo), Fu Fanji 傅汎際 (Francisco Furtado) and Tang Ruowang 湯若望 (Adam Schall).
Folio 1r gives the title of the book and the name of the author: 遠西耶穌會士羅雅谷著. It also says that the text was read and improved by Li Tianjing 李天經 of Yinghai 瀛海 (Hebei).
There are nine columns in each half folio with nineteen characters in the first column of each paragraph and eighteen in the rest of the paragraph. The title of the book is given in the upper middle of each folio with the number of the folio marked below.

Both the arrangement and the format of this book are the same as those of the Tianzhujing jie 天主經解 (Jap-Sin I,, 147a). The Hail Mary is explained in full. It begins with a general introduction followed by the prayer divided into sections according to its meaning. Especially great attention is given to the explanation of the holy name of Jesus.
