The Jia day master is the first of the ten heavenly stems in traditional Chinese astrology, representing Yang Wood. It is the stem that occupies the "day pillar" position in a person's Four Pillars (BaZi) chart, traditionally treated as the core marker of one's inner nature.
In folk symbolism, Jia is likened to a tall, upright tree standing in open ground — something that grows straight, reaches for the sky, and does not easily bend. Jia day masters are traditionally described as principled, direct, and driven, often taking the lead and preferring clear rules over ambiguity. This same steadiness is also traditionally read as a tendency toward stubbornness or difficulty compromising.
Traditional five-element theory holds that a Jia Wood day master generally benefits from water, which is said to nourish a tree's growth, and welcomes a measure of metal, said to prune and shape it into useful form. Excessive wood alongside it is traditionally read as crowding rather than reinforcement. This growth-and-pruning pairing is long-standing folk symbolism rather than a fixed rule, and any complete reading weighs the chart as a whole, not one stem alone.
