Tetragram for Full Circle

It names 周, the second Tai Xuan figure, and suggests cyclical return.

A tetragram here is a four-line sign built from three kinds of line: solid, broken once, or broken twice. The Tai Xuan Jing, a Chinese divination classic, models its system on the Yijing (the Book of Changes), but gives each figure its own name and text.

The Tai Xuan passage for 周 describes yang, one of the text’s paired cosmic forces, circling back to its beginning as things follow their kind. “Full circle” is an English gloss for 周, pointing to cyclical return rather than a generic chat signal.

Where did this tetragram come from?

Yang Xiong composed the work around 2 BCE. The earliest surviving version is associated with Fan Wang’s Jin dynasty edition, which places each figure beside its verse and short interpretations of its lines.

The Tai Xuan Jing supplemented the Yijing: readers used changing line patterns to interpret a situation and guide conduct. Each figure combines four lines, a name, a poetic image, and short interpretations.

One documented later edition places 𝌇 at the start of a vertical Chinese text column, marking the Zhou passage that follows.

Is 𝌇 a circle symbol or an emoji?

Treat it as a historical text sign, not a general-purpose emoji.

Its specific reading belongs to the Zhou passage and its interpretations. Sent alone in everyday chat, it has no settled modern message. If it arrives without the Tai Xuan context, ask what the sender means before reading it as “circle back,” completion, or a mood.
