1. What is a bureau?
A three-Branch bureau is three characters from different seats, allied for one aim, at that element’s birth, peak, and grave-vault. Yin-Wu-Xu are Fire’s birth, peak, and grave; together they fuse into one blazing body of Fire.

2. What a Fire bureau means
Fire governs propriety, passion, fame, and a burst of drive. If Fire is your favorable element, a Yin-Wu-Xu Fire bureau brings fame, momentum, and full-on drive, a force that gets things blazing; if Fire is unfavorable, too much brings restlessness, haste, burnout, and loss. Of the three, Wu (the peak) is the core.
3. Only two? — the half-combination
With Yin-Wu or Wu-Xu (carrying the peak, Wu), it half-combines into Fire: reduced but real; missing Wu, with only Yin and Xu, it is an “Arch,” real only once a Luck Pillar or year fills it in.
4. When does it form? — filling in
With two of Yin-Wu-Xu present, a Luck Pillar or year supplies the third and the Fire bureau forms for that stretch, flooding the chart. With a bureau, the key is which year completes it.
5. Good or bad?
It depends on your chart’s needs. Favor Fire and it is the sun at zenith, fame for a season; fear Fire and it is restless burnout, too much of a good thing. The greater the force, the more pronounced either way.
6. Example: Yin in the Month, Xu in the Day, a Luck Pillar supplies Wu
This is a made-up example for illustration, not a real person’s chart. Picture a man’s chart: Year Bing-Chen (丙辰), Month Geng-Yin (庚寅), Day Geng-Xu (庚戌), Hour Wu-Yin (戊寅). The Month Branch is Yin and the Day Branch Xu; the Fire bureau is missing its peak, Wu, and the Hour Branch holds another Yin. The Day Master is Geng Metal; Fire is Geng’s Officer and Killings, and Bing Fire already shows on the Year Stem. This chart’s fourth Luck Pillar is Jia-Wu (roughly ages 33 to 43); once Wu arrives, the Yin-Wu-Xu Fire bureau forms and the Officer and Killings grow much heavier over these ten years. On favorability: Geng Metal born in a Yin month is out of season, so the self is not strong; with the Fire bureau formed, Officer and Killings press on the self, often showing as heavier duties, more demands, and clear pressure. If the Resource stars in the chart (Wu Earth, Chen Earth) are strong and can turn the Fire into support for the self, this pressure can become a rise in position and reputation; if Resource is weak, it’s wise to keep workload and responsibilities within what you can carry.
