Longduoduo is a healthcare sales agency operating in China that markets and sells preventive healthcare packages directly to individual consumers, primarily in Inner Mongolia. The company does not operate medical facilities or employ physicians; licensed third-party hospitals and clinics deliver all medical treatments. Longduoduo acts primarily as a sales agent for Honghai, a third-party healthcare provider. Under this agency model, Longduoduo acquires customers, collects payments, and remits the proceeds to Honghai while retaining a sales commission, while Honghai assumes liability for treatment quality. The health maintenance packages Longduoduo markets focus on preventing and managing cardiovascular, cerebrovascular, and gastrointestinal diseases. Offerings include ozone-based blood treatments, double blood purification therapies, traditional Chinese medicine treatments, and gut microbiota testing products. Revenue is transaction-based and depends on the volume of services sold. Longduoduo's strategy centers on expanding its geographic presence across China beyond Inner Mongolia, broadening its service offerings beyond Honghai, and upgrading its customer support operations.
