Feng shui has developed into several distinct schools over its long history, each offering valuable tools for reading and adjusting the energy of spaces. The Form School, the oldest approach, focuses on the physical landscape and the shapes of the natural environment. Practitioners evaluate how mountains, rivers, roads, and neighboring buildings direct or block the flow of chi toward a site. Inside the home, the Form School examines furniture placement, room proportions, and the visual relationships between objects to ensure comfortable, balanced energy flow.

The Compass School, which developed later, introduces mathematical precision through the use of the luo pan, a specialized feng shui compass. This approach divides space into sectors based on compass directions, each associated with specific life areas, elements, and trigrams from the I Ching. The Flying Stars method, a sophisticated branch of Compass School feng shui, maps time-based energy patterns onto a building's floor plan, revealing how the quality of chi in each sector shifts over months and years.

Many contemporary practitioners blend these classical approaches with an intuitive method sometimes called Black Hat or BTB feng shui. This modern approach, popularized in the West, uses the main entrance rather than compass readings to orient the bagua map. It emphasizes intention-setting, visualization, and the personal relationship between occupant and space. While purists may debate which school is most accurate, experienced practitioners recognize that each approach illuminates different aspects of a space's energy. The most effective practice often combines elements from all three traditions.
