Longduoduo Co Ltd (LDDD) is a China-based preventive healthcare services company that markets and sells healthcare treatments to individual consumers in Inner Mongolia. The company earns revenue through two models: as a principal, purchasing and reselling services from licensed third-party healthcare providers, and as a sales agent for Honghai, collecting payments and retaining a commission on each transaction. Principal-based service revenue fell nearly 63% in the fiscal year ended June 30, 2025 versus the fiscal year ended June 30, 2024. The company operates through subsidiaries including Qingguo, Rongbin, Chengheng, Tianju, and Longduoduo Health Technology, and employed 52 full-time staff as of the 10-K filed September 26, 2025. It is incorporated as a holding structure with a Hong Kong intermediate entity and principal PRC operations under Julong. The company has not yet secured a U.S. exchange listing and intends to raise capital abroad to fund growth of its PRC subsidiary.
