Tetragram for Centre

It names the opening unit 中, called “Center.” The unit belongs to the Tai Xuan Jing, a Han-era Chinese divination classic by Yang Xiong, first drafted around 2 BCE.

The book follows the Yijing, or Book of Changes, but builds its figures from four stacked lines, each solid, split once, or split twice. The three line forms connect to Heaven, Earth, and Humanity. Read the lines from top to bottom; each figure comes with nine short judgments that trace a changing situation.

The Center passage says yang—the active force paired with yin—starts to sprout in the Yellow Palace, and that reliability lies in the center. A Jin dynasty revision by Fan Wang set the judgments beside each sign. An academy tradition in the late Han and Wei-Jin period taught the Tai Xuan alongside the Zhou Yi, another name for the Book of Changes; Song dynasty critics challenged Yang Xiong’s project. A 2021 scholarly reading also treats the work as philosophy alongside divination.

What does 𝌆 mean when someone sends it?

Treat it as a reference until you know the sender’s context. They may be naming the Center unit, quoting the book, or checking whether the glyph displays; the lone sign does not establish a personal message. Ask what passage or idea they mean.

If you send it, label it as Tai Xuan Jing notation or include the passage it refers to, so the other person knows what to read.

Why can 𝌆 look different across fonts?

A font or app may not contain a glyph for it. If it appears as a box or fallback mark on the recipient’s device, that is a display limitation, not a different sign. Its shape depends on the fonts the app can use.
