Feng Shui had a long history.
The concept started thriving in Wei-Jin period and consisted of two major schools, namely the Form School established by Yang Yunsong in late Tang Dynasty and the Compass School founded by Wang Ji in Song Dynasty.
The Form School emphasized on searching for the right mountains, observing water, seeking mounds, and selecting sites. The good or bad luck was to be determined by the Qi of the place. The Compass School, on the other hand, took ideas from Bagua and five stars to determine the interactions of the three key positions (the entrance, the main room, and the kitchen) and six matters (doors, corridors, stoves, wells, beds, and toilets) of a dwelling.
In simple terms, the Form School was good at field work, while the Compass School did better job indoors.
