Wen Ku is a perfume brand owned by Beijing Yitian Times Trading Co., Ltd., established in 2009, and is one of the earliest players involved in perfume in China. The odor library has formed a multi-category pattern composed of four major plates: perfume, home fragrance, fragrance body care and fragrance body gift box.

Smell database combines the product with humanistic attributes and story attributes, so that the product no longer stays at the level of perfume objects, but is a meaningful and valuable emotional product.
