Feng Shui teaches in which way design, styling and the interior of your living environment are affecting your well-being and happiness, and also how negative influences may be altered into positive. Feng Shui is about the relationship between man and the living environment, including the workplace, and aims at harmonising natural and created configurations. Everything we create is essentially not natural, but can be harmonised with nature. Feng Shui aims at adapting our living or working environment in ways that stimulate a harmonious flow of Chi (life force). In Chinese philosophy, it is all about harmony and balance between the complementary forces of yin and yang, like male and female, etc.
