The fragrance comes first, the next is brilliant, and the smell is brilliant, that is, the fragrance. HELI DESIGN aims at the new business travel concept, focusing on the relationship between people, space and anyone, and creating an olfactory recognition system that conforms to its brand concept for various brands of hotels under the Huamu Department. The concept of the fragrance machine product is taken from the meaning of flower blooming, extending from the center to the outside, opening layer by layer, interspersed with lines, creating a level of beauty, and visually presenting the fragrance.
