Reading this star map
Girl forms a narrow, open outline of four stars. The reference lies at lower right; a long segment runs between the lower-left and upper-left stars, and a fourth lies at upper right. These are projected positions, not a flat arrangement of stars in physical space.
Understanding the deity title
The traditional title 女土蝠 (Nu Tu Fu) combines the mansion character 女, the association 土, and the animal image 蝠. The astronomical entry is Girl Mansion. A deity portrait expresses cultural imagery; a star map records positions and connecting lines. They can be read together without expecting the star pattern to resemble the animal.
What does this calculator result mean?
If a birthday lookup returns this mansion, the entered date is assigned to it by our daily almanac rules. It does not mean everyone born that day shares a personality, or that the Moon was inside this star pattern. Compare calendar, date and assignment system before comparing tools.

The historical text describes the roles of celestial asterisms. The life and personality associations below are our modern interpretations, not historical claims about people born on a particular date.
「主布帛裁制嫁娶」《晉書》卷十一・天文志上・二十八舍Nü is associated with making textiles and marriage arrangements. A modern metaphor is the quiet skill of getting practical details right. These tasks do not belong to one gender, and careful work deserves recognition and shared effort rather than being taken for granted.
