There are feng shui courses with different orientations: some courses teach the classical Chinese school, others offer courses in which the traditional theory of harmony is adapted to a greater or lesser extent to European conditions. Less traditional courses sometimes also include geomantic elements or spatial psychology. Here you have to decide which direction of Feng Shui you want to take.
Depending on whether you would like to train in feng shui purely out of interest, with a view to freelance work or as a supplement to your existing professional activity, some training courses are more suitable than others. If in doubt, ask the course providers directly for more information about the training or for a personal consultation.
