# Xuan Kong Flying Stars (玄空飞星)

> Xuan Kong Flying Stars is a feng shui school in which nine stars, numbered 1 to 9, fly through the nine palaces in Lo Shu order. Their positions depend on the 20-year period and on the house's sitting and facing, so the same orientation reads differently in each period.

## Explanation

Each period lasts 20 years; three periods make a cycle of 60 years and three cycles make 180 years. The years 2024–2043 are Period 9. From the period star, the mountain and facing stars are placed in the nine palaces to build the house's star chart.

The school was systematised by Shen Zhureng in the late Qing dynasty, published as Shen's Study of Xuan Kong, and is still widely used.
