Qingyang Qihuang Culture Communication Co., Ltd. was established in 2002 and is located in Qingyang City, Gansu Province. It is an enterprise mainly engaged in the cultural and artistic industry.

The sachets made by Liu Lanfang not only inherit the rich styles of their predecessors, but also retain the naivety and simplicity of folk handicrafts, expressing emotions in things and conveying emotions from things. Her sachets are exquisitely made of materials, from color matching, structure to shape and connotation, retaining traditional regional characteristics and technical characteristics with practicality as the main body.

In 2002, Liu Lanfang took her carefully sewn sachets to participate in the first China Vaccinia Folk Culture Festival held in Qingyang City, and the result was very popular. Soon, she went to Shanghai to attend the Folk Culture Expo, and the sachets were also sold out. After returning, she immediately registered Qingyang Qihuang Culture Communication Co., Ltd. and served as the company's general manager and design director.

The sachets made by Liu Lanfang and the children went out of Qingyang, sold to the whole country, and even to the world. Taking advantage of Gansu's efforts to promote the construction of the Silk Road Economic Belt and the China Civilization Inheritance and Innovation Zone, they have successively gone to the United States, Canada, Belarus, Italy and other countries to promote Qingyang sachets, winning unanimous praise from the international market. Liu Lanfang also held lectures and performances at Yale, Harvard and other universities to spread China's excellent traditional culture.
