What is Nạp Âm?
Na Yin is a system that assigns names and Five Elements attributes to each pair of Heavenly Stems and Earthly Branches in the Sixty Jiazi cycle, used for interpreting destiny and fortune.
Also called: Nạp Âm (Sound Element)

What is Nạp Âm?
Nạp Âm (納音) is a method that combines a Heavenly Stem (Can) and an Earthly Branch (Chi) to create a new name, along with its Five Elements (Ngũ Hành) attribute, for each of the 60 pairs in the Lục Thập Hoa Giáp (the 60-year cycle). Each Stem-Branch pair such as Giáp Tý or Ất Sửu is assigned its own nạp âm, for example Hải Trung Kim (Gold in the Sea) or Lư Trung Hỏa (Fire in the Stove). These names usually carry metaphorical imagery and are used to interpret personality and fortune, as well as in feng shui, date selection and age compatibility.
What is the origin and principle of Nạp Âm?
By tradition, Nạp Âm originates from the theory of Can Chi and Ngũ Hành, and may have appeared as early as the Han dynasty or earlier in ancient calendrical texts. The calculation is based on the interaction between Can and Chi, usually through the nạp âm Five Elements of the Can and the Chi, or by using a ready-made lookup table. Each nạp âm is named after a concrete image, such as water in a ravine (Đại Khê Thủy), gold beneath the sea (Hải Trung Kim), or fire in a stove (Lư Trung Hỏa). The name not only describes the element but also hints at its nature and at how strong or weak that element is.
How is Nạp Âm used in practice?
In Tử Vi (Vietnamese astrology) and feng shui, Nạp Âm is often used to determine a person's mệnh (destiny element) based on their year of birth. For instance, a person born in the year of Giáp Tý is considered to have the mệnh Hải Trung Kim. In addition, nạp âm is used to select auspicious or inauspicious days and hours, to examine compatibility and conflict between ages, or to supplement the Five Elements in the arrangement of a house. It should be noted, however, that this is traditional knowledge of a reference nature, not verified by science.
How do you distinguish Nạp Âm from easily confused terms?
Nạp Âm differs from the Five Elements of the Can and the Chi taken separately. Each Can and each Chi has its own element, but nạp âm is the combined element of the whole pair, and it may differ. For example, Giáp belongs to Mộc (Wood) and Tý belongs to Thủy (Water), yet the nạp âm of Giáp Tý is Kim (Metal), namely Hải Trung Kim. Nạp Âm is also not identical to "mệnh" in the sense of one's native element, since mệnh can be understood as the element of the birth year according to nạp âm, though it is sometimes understood differently. Furthermore, Nạp Âm is not an independent system but part of the broader theory of Can Chi.
What should you keep in mind when using Nạp Âm?
Nạp Âm is a concept within traditional metaphysics and is of a reference nature. Readers should combine it with other factors and should not treat it as absolute truth.
How do the different schools understand Nạp Âm?
- The calendrical understanding: Nạp Âm is seen as a tool for encoding and memorising the 60 Stem-Branch combinations, making calendrical lookup and calculation more convenient. The names are merely conventional and are rarely used to interpret fate.
- The fate-analysis understanding: Nạp Âm is used to determine a person's native Five Elements destiny, from which personality, fortune and compatible or conflicting relationships are interpreted. Each nạp âm carries deep symbolic meaning that influences a person's life.
- The feng shui understanding: Nạp Âm is applied to choose house orientation, colours and feng shui objects suited to each age, in order to balance and supplement the energy of the Five Elements.

Each nạp âm name is shared by exactly two consecutive Stem-Branch pairs, so the 60 pairs yield only 30 names. The nạp âm element is the element people are asking about when they say "what mệnh is this age", and it differs from the element of the Can alone and the Chi alone.
The figures in the table match the results of the lookup tools on Nhật Nguyệt.
