1.In-depth Company Introduction
Company Name : Nanjing DeRun Classic Tea Culture Co., Ltd.
One-sentence Positioning
With tea as the vehicle of Dao and fragrance as the bearer of Dao; between tradition and modernity, we present Oriental life aesthetics to the world - Nanjing DeRun Classic Tea Culture inheriting classics and conducting business with craftsmanship.
Corporate Vision and Mission
DeRun Classic Tea Culture is committed to integrating "tea, utensils, fragrance, Zen, and cultivation" to build an Oriental life art brand with long-term vitality. We believe that corporate profitability is not only for survival and growth, but also should become a source of strength for cultural inheritance, social feedback, and global communication. The company will continue to take product strength as the foundation, culture as the soul, and use fund and platform mechanisms to turn "inheritance" into sustainable actions.
Corporate Story and Founder
DeRun Classic Tea Culture originated from Jinling (Nanjing) - nurtured by the cultural heritage of this ancient capital of six dynasties and the vital energy of the landscape and countryside in Gaochun International Slow City. The founder's courtesy name is Xuanyi. "Xuan" (profound/mysterious) implies depth and subtlety, corresponding to the Taoist "Xuan" (mystery) philosophy and the principle of harmony between heaven and humanity; "Yi" (the one) symbolizes returning to the origin, the primeval state, and the innate vital energy. The name "Xuanyi" not only inherits the Taoist meaning of the primeval state and the natural flow of vital energy, but also embodies the cultural essence of Buddhism's return to simplicity and Confucianism's emphasis on self-cultivation and family governance. Through long-term study and practice of Taoism, Buddhism, tea, fragrance, and intangible cultural heritage craftsmanship, the founder established the corporate philosophy of "the unity of Dao and utensils, and the parallel development of tea fragrance appreciation and self-cultivation", thus founding DeRun Classic Tea Culture. It is hoped that this concept of "nourishing all things with virtue and nurturing the mind with tea" will develop into an undertaking that can be remembered by the times for a long time.
Corporate Development Philosophy (Values)
Virtue as the Foundation, Craftsmanship as the Tool: With the two characters "DeRun" (nourishing with virtue) as the core - taking virtue as the foundation of the enterprise; applying the spirit of craftsmanship in designing or carefully selecting every type of tea and utensil. Unity of Object and Mind: Products not only have material value, but also carry the connotations of self-cultivation, etiquette, aesthetics, and life philosophy.
Sustainable Inheritance: Using commercial methods to ensure the inheritance of traditional techniques, tea art, and health preservation methods. Profit as Support: The first priority of profits is to support the company's growth and employee rewards; the second is to invest in brand culture promotion and the research and development of classic products; the third is to establish the "DeRun · Hongdao Fund" to support cultural communication, education, and charitable practices.
International Mutual Learning: Promoting dialogue between Chinese tea, fragrance, utensils and the life aesthetics of various countries around the world, and striving to become a "Chinese business card" with cultural influence.
