# Taixuanjing

The Taixuanjing is a divination guide composed by the Confucian writer Yang Xiong (53 BCE – 18 CE) in the decade prior to the fall of the Western Han dynasty. The first draft of this work was completed in 2 BCE; during the Jin dynasty, an otherwise unknown person named Fan Wang (范望) salvaged the text and wrote a commentary on it, from which our text survives today.

## Content

The Taixuanjing is a divinatory text similar to, and inspired by, the I Ching. The I Ching is based on 64 binary hexagrams—characters composed of six horizontal lines, with each line either broken or unbroken. Meanwhile, the Taixuanjing is based on 81 ternary tetragrams—characters composed of four lines, with each line either unbroken, broken once, or broken twice. Like the I Ching, it may be consulted as an oracle by casting yarrow stalks or a six-faced die to generate numbers which define the lines of the tetragram, which is then looked up in the text.
A tetragram drawn without moving lines refers to the tetragram description, while a tetragram drawn with moving lines refers to the specific lines.
The monograms are:
* the unbroken line ( ⚊) for heaven (天; tiān),
* once broken line ( ⚋) for earth (地; dì),
* twice broken line ( 𝌀) for man (人; rén).
Numerically the symbols can be counted as ⚊ = 0, ⚋ = 1, 𝌀 = 2, and grouped into sets of four to count from 0 to 80. This is clearly intentional as this passage from chapter 8 of the Taixuanjing points out the principle of carrying and place value.

Second Part: one doesn't add, two adds three, three adds six. Third Part: one doesn't add, two adds nine, three adds eighteen. Fourth Part: one doesn't add, two adds twenty-seven, three adds fifty-four. |

## Unicode

In the Unicode Standard, the Tai Xuan Jing Symbols block is an extension of the I Ching symbols. Their Chinese aliases most accurately reflect their interpretation; for example, the Chinese alias of code point U+1D300 is "rén", which translates into English as man and yet the English alias is "MONOGRAM FOR EARTH".
