卷二 supplies its own worked example here. A person born in a 甲 year with the 命宮 at 寅 has the stem 丙, because 甲 and 己 years begin at 丙寅, and 丙寅 falls under 爐中火 in the 納音 song, so the chart is in the fire bureau. The other five fire names are 山頭火, 霹靂火, 山下火, 覆燈火 and 天上火.

Six is the largest divisor, so the first days of the month reach furthest from 寅. The book states that day one begins at 酉, and its verse gives day two at 午, on a horse, and day four at 辰, on a dragon. Arithmetic agrees: day one adds five, an odd number, and moves back five from 寅 to 酉, while day two adds four and moves forward to 午. The book's own warning about this count is that a small slip here throws off everything after it.

The first ten-year period in this bureau opens at age six, which is as late as any chart begins. That age comes from the number and the verse, and the book states no general rule for it. The default chart begins on the 命宮 and the book setting one palace away. The 長生 stages start at 寅, as the book's list has it.
