Longduoduo is a small holding company incorporated in Nevada that operates entirely through subsidiaries in China, focused on selling preventive healthcare services targeting cardiovascular and cerebrovascular conditions to individual customers in Inner Mongolia and northern China. The company does not own or operate medical facilities — it is a sales and marketing intermediary. Longduoduo operates primarily as a commissioned sales agent for a single third-party healthcare provider, Inner Mongolia Honghai Health Management, which accounts for over 97% of gross revenue. Under this model, Longduoduo sells Honghai's health maintenance services to end customers, collects payment, and remits it to Honghai while keeping a pre-agreed commission. Longduoduo also buys and resells preventive healthcare services directly from licensed hospitals and clinics in cities including Hohhot, Baotou, Ordos, and Ulanqab — offering treatments such as ozone autohemotherapy, blood purification, and traditional Chinese medicine therapies — but this principal sales business has declined sharply and now represents a small share of revenue. With just 52 employees, Longduoduo is a regional intermediary with no proprietary medical assets. The company's stated goal is to expand geographically across China and diversify its provider relationships beyond the current dependence on Honghai, though that growth plan relies on raising capital through a U.S. exchange listing, which remains uncertain.
