Tall Tree
Jia Wood is the first of the ten Heavenly Stems and the yang side of Wood. On this page you can see how AevoStar interprets the Jia Wood Day Master, where it sits among the elements and on the yin-yang scale, how the other nine stems relate to it, and a few common myths.
Picture the hour just before sunrise, when a tall trunk starts to show against a paling sky. That is the scene AevoStar uses for Jia Wood. Read that way, Jia Wood is a temperament that sets a direction first and then grows toward it steadily. You often see it described as the one who walks ahead where no path exists yet, or who writes the first draft of a rule. A trunk that grows straight can find it awkward to bend around obstacles, so taking the long way may feel unnatural at first. The same picture also carries staying power: once something is planted, Jia Wood tends to keep tending it until it is grown. Keep in mind that this is a reading of one character out of eight. In a chart with plenty of Water and Wood around it, the urge to reach outward can run high, and several projects may start at once. With fewer supporting characters, the big direction usually holds while the pace becomes something you choose with care. Neither version is the better one. We read the same tree together with the weather it grew in, which is why your full chart matters more than this page.
Among the Five Elements, Jia Wood belongs to Wood, and on the yin-yang side it is yang. Yi Wood, the yin form of Wood, shares its element, which is why the two carry the Ten Gods name Rival for each other. Where Jia Wood is the main trunk rising in one line, Yi Wood is closer to the branches and vines that spread around it. Sharing an element does not make two Day Masters the same, and this page keeps that difference in view.

The relation names in this section describe characters inside one chart; they are not a compatibility verdict between two people. The table shows what each of the other nine stems is to Jia Wood. Water stems, which feed Wood, appear in the Resource group; Fire stems, which Wood feeds, appear as Output; Earth stems, which Wood holds in place with its roots, appear as Wealth; and Metal stems, which trim Wood, appear as Officer. Among the Earth that the roots grip, Ji Earth is the combination partner: Direct Wealth in the table, and a pair said to pull toward Earth. From the Metal that trims branches, Geng Metal stands opposite as the clash partner, listed as Indirect Officer. The label alone decides nothing.
The same Day Master splits into ten type names, depending on how the five elements lean.
Myth
The Jia Wood Day Master is too stubborn to listen.
In fact
This comes from the image of a trunk that grows straight. AevoStar reads it as a habit of fixing a direction early, nothing more, and whether someone listens depends on the other seven characters and the current stretch of time.
Myth
Being first, Jia Wood is the strongest of the ten stems.
In fact
First place in the order is a position, not a rank. The ten stems run in a loop, and none of them sits above or below the others.
Both belong to Wood, but Jia Wood is yang and Yi Wood is yin. AevoStar draws Jia Wood as one trunk climbing straight up and Yi Wood as growth that spreads along gaps and follows the wind. Given the same goal, Jia Wood tends to cut a direct path while Yi Wood looks for a way around first. In a real chart, the surrounding characters can widen or narrow this gap.
A type name combines the Day Master with how much of each element the whole chart holds. So the same Jia Wood Day Master splits into ten names depending on which element runs high or low. The names that can appear for Jia Wood are listed further down this page. Enter your birth details to see yours.
Ji Earth is the stem that forms a stem combination with Jia Wood. Wood holds Earth in place with its roots, and the two have opposite yin-yang, so the Ten Gods name is Direct Wealth. Direct Wealth points to results you build up steadily and things you look after with care, so the partner reads as the side Jia Wood cultivates. It does not decide who you should meet.
