How to Read Nayin: Another Layer of the Sixty Jiazi

The Concept of Nayin (纳音)

Nayin Five Elements (纳音五行) is another unique Five Element (五行) classification method within the sixty Jiazi (六十甲子) system. It groups the sixty Stem-Branch pairs into thirty Nayin (纳音) pairs according to the laws of ancient musical pitch, with each pair corresponding to a Five Element (五行) attribute. Nayin (纳音) theory originates from the deep integration of ancient musical pitch studies (the five notes and twelve pitches, 五音十二律) and Five Element (五行) thought, providing a more detailed and deeper dimension of Five Element (五行) judgment for destiny analysis. The name \"Nayin\" (纳音, receiving the note) means incorporating the notes of the Stems and Branches into the Five Elements (五行), reflecting the ancient Chinese philosophical idea of \"the unity of heaven and humanity.\"

Overview of the Thirty Nayin Pairs (三十对纳音概览)

Every two groups of Stems and Branches in the sixty Jiazi (六十甲子) share one Nayin (纳音) name, forming thirty pairs of Nayin (纳音). Nayin names mostly use specific substances from the natural world, such as \"Metal in the Sea\" (海中金), \"Fire in the Furnace\" (炉中火), and \"Great Forest Wood\" (大林木), vividly and intuitively expressing the Five Element (五行) characteristics of that group of Stems and Branches. This method of using objects to illustrate principles makes the abstract Five Element (五行) concepts concrete and perceptible, facilitating understanding and memory.
