Perfume can simply symbolically mean spiritual experience. However, it was reported in Science and the Guardian that your perfume, petro-chemical based, has a heavy footprint and may be a major cause of air pollution. What’s worse, numerous people are not able to to use up the whole bottle. Therefore, we create a perfume sharing system, Aromall, to help everyone live an exquisite life, which also helps build a harmonious and sustainable society with equality. Aromall manages to make personalized customization and carry forward traditional taoism culture.
