Water Na Yin: Spring, Stream, River and Sea Labels Explained

一 What it is

Water Na Yin names are six fixed names, each shared by two adjacent stem–branch entries, that describe the setting in which a Water image appears, not how much counted Water a chart contains. Think of the difference between a kitchen tap, a garden spring, a canal, a raincloud, a mountain torrent and the open ocean: each suggests a different scene and scale, yet none of them tells you the volume of water actually present in the room. That is the distinctive feature of this group. All six share the element Water, so they are not separated by element but by image and position in the cycle. The six names are Stream Water (涧下水), Spring Water (泉中水), Long-Flowing Water (长流水), Heavenly River Water (天河水), Great Stream Water (大溪水) and Great Sea Water (大海水). Each is tied to a complete valid stem-branch pair, and the pair is what you match, not a single character. Because the label is attached to the pair, two pillars with the same Na Yin element can still look completely different once you read their visible stems and hidden stems. This is why what Na Yin labels actually record matters: they are a naming layer over the sexagenary cycle, not a second set of hidden stems.

二 Where to find it in your chart

On the calculator, the Four Pillars grid shows Year, Month, Day and Hour. Each position has a top stem, a bottom branch, and small hidden stem characters listed under the branch. The main interface has no dedicated Na Yin row and no growth phase row, and it does not print every hidden Ten God label. To use this guide, copy a complete valid pair from the position you want, for example the day pillar or the month pillar, then match that pair in the six-row lookup below. If the pair is not listed in the six Water rows, consult the complete thirty-name table instead of forcing a match. The Day Master is the Day stem alone, so a Jia day stem stays Jia regardless of any Na Yin label. If the birth hour is unknown, the hour pillar is unconfirmed and should not be matched. Once you have the pair, you can calculate your chart and read the label in context.

三 How to read the six names

The six names are best treated as six different camera distances. Stream Water (涧下水) is the smallest image: water running in a narrow ravine, easy to miss and easy to step over. Spring Water (泉中水) is water rising from underground, quiet and local, appearing where the ground opens. Long-Flowing Water (长流水) is a channel that keeps moving over distance, less about a single source and more about continuity. Heavenly River Water (天河水) is the sky river, rain or the Milky Way, water imagined above the earth rather than pooled in it. Great Stream Water (大溪水) is a broad mountain torrent, faster and wider than a ravine. Great Sea Water (大海水) is the open sea, the largest container in the set. These are teaching metaphors, not fixed rules that one element needs another, and they are not personality predictions.

Keep the canonical Chinese labels and the English glosses shown here together. The translations are editorial conveniences, not universal standards, so 涧下水 is rendered here as Stream Water and 大溪水 as Great Stream Water even though both contain the idea of a stream. The distinction is scale and setting, not amount. A chart can carry a Water Na Yin label while its visible stems and hidden stems show little or no literal Water, and a chart can show several Water stems while carrying no Water Na Yin label at all.

To look a name up, take the complete pair from one position. For example, 甲申 and 乙酉 share Spring Water; 丙午 and 丁未 share Heavenly River Water. The pair is the key. Do not split it into a stem and a branch and match them separately, because the Na Yin assignment belongs to the whole pillar. The six-row table below gives two cycle indexes and two complete pairs for each name, so you can confirm the match before reading anything else.

After matching, return to the chart and read the actual stems and hidden stems. The label tells you which image the pair carries; the stems and hidden stems tell you what elements are represented by stems. The complete thirty-name Na Yin table is the reference for pairs outside this Water group. Growth phases are a separate stem-branch lookup and are never derived from Na Yin, so a Na Yin name does not generate a phase and a phase does not generate a Na Yin name.

四 When the reading changes

Same Na Yin element, different name

Two pillars can both carry Water Na Yin and still be different names. Spring Water and Great Sea Water share the element but not the image, and they sit at different cycle indexes. Check the pair first, then the name. Different pairs can share one name when they occupy the same paired row; compare the row, not only the characters. The teaching charts illustrate two different Water rows: 甲申 is Spring Water in A, while 丙午 is Heavenly River Water in B.

Target column with or without literal element stems

A Water Na Yin label does not guarantee a Water stem in that column. Look at the top stem and the hidden stems of the target pillar. If the stem is Fire and the hidden stems are Fire and Earth, the column has no Water stem even though its Na Yin element is Water. Only claim a column lacks an element when its stem and hidden stems actually show that. In Chart B the month pillar 丙午 carries Heavenly River Water, and its stem Bing and hidden Ding are Fire, so the column shows no Water stem at all.

Same Day Master, different labels

Both teaching charts use Jia Yang Wood as the Day Master, yet their target Water Na Yin names differ: Spring Water in one, Heavenly River Water in the other. The Day Master is unchanged, so any difference you observe comes from the pillars, not from the day stem. Use the exact-pair Na Yin lookup method to confirm each target before comparing. Chart A places Spring Water in the day pillar and Chart B places Heavenly River Water in the month pillar, so the position of the label differs as well as the name.

Actual stem and hidden element totals versus labels

Weighted element totals come from visible stems and hidden stems, not from Na Yin names. A Water Na Yin label never adds a hidden stem, never changes a Ten God, and never adds to the weighted totals. Compare the totals directly when you want to know which elements are represented by stems, and treat the label as a separate naming layer. Chart A totals Water at 1 and Chart B totals Water at 2, and those figures come from visible and hidden stems rather than from either Water Na Yin name.

五 Worked chart examples

Calendar-screened teaching charts, not client biographies. Both use a Jia Yang Wood Day Master. Each has exactly one Water Na Yin label, at the position identified in the explanation; actual element stems are counted separately.

Chart A has pillars 辛未, 辛丑, 甲申 and 己巳. The target Water Na Yin sits in the day pillar, 甲申, whose Na Yin is Spring Water (泉中水). The day stem is Jia Wood, the Day Master, and the day branch is Shen, a Metal branch. Shen hides Geng Metal, Ren Water and Wu Earth. Geng is Seven Killings for Jia, Ren is Indirect Resource, and Wu is Indirect Wealth. Ren Water is therefore an Indirect Resource for Jia, never a same-element root for Jia. The visible day stem is Wood, and the only Water in this column is hidden Ren at weight 0.5. The chart's actual Water element total is 1, and that figure comes from the stems and hidden stems, not from the Spring Water label.

Two decisive checks follow. First, confirm the pair: 甲申 is one of the two Spring Water pairs, so the label is correct. Second, confirm the element: the day column shows a Wood stem and a Metal branch with hidden Metal, Water and Earth, so the column contains hidden Water but no visible Water stem. The label does not add a Water stem, and it does not turn Ren into a Wood root. Jia's same-element roots come from hidden Jia or Yi, which give Wood roots; only Jia is a same-stem root. A visible peer is not a hidden root, and the Spring Water name does not change any of this.

Because the day branch Shen hides Ren, that Resource sits in the same column as the Spring Water label.

Chart B has pillars 壬午, 丙午, 甲子 and 己巳. The target Water Na Yin sits in the month pillar, 丙午, whose Na Yin is Heavenly River Water (天河水). The month stem is Bing Fire and the month branch is Wu Fire, and the hidden stems are Ding Fire and Ji Earth. There is no Water stem in the target column, visible or hidden, even though the Na Yin element is Water. The chart's actual Water element total is 2, coming from the year stem Ren and the day branch Zi's hidden Gui, not from the Heavenly River label.

The year stem Ren and the day branch Zi hidden Gui supply the chart's Water, while the month pillar 丙午 carries the Heavenly River Water label with a Fire stem and Fire branch and hidden Ding Fire and Ji Earth, so the label and the literal Water sit in different columns.

Compared with Chart A, the year pillar differs (辛未 versus 壬午), the month pillar differs (辛丑 versus 丙午), and the day pillar differs (甲申 versus 甲子). The hour pillar is unchanged: both charts use 己巳. This is a comparison of two fixed teaching charts, not a controlled experiment and not a chronological life story. The target Na Yin stays at its actual position in each chart: Spring Water in the day pillar of A, Heavenly River Water in the month pillar of B. A practical reader check is to open the hidden stems and their weights and verify the target column’s actual stems separately from the Na Yin label, rather than assuming the label supplies the element.

六 What the counts mean

This Water group contains six Na Yin names covering twelve of the sixty sexagenary-cycle entries. Each name belongs to two adjacent cycle entries. These are lookup-table counts, not a population distribution or a probability of any life outcome. They do not describe how much Water is present in a chart’s weighted element totals.

Calculation reference: the calendar library’s Na Yin mapping. Chinese labels follow the verified table; English names are editorial glosses. No Na Yin element is added to the calculator’s stem-based totals.
