Runjian Co., Ltd. (润建股份), a Shenzhen-listed enterprise under stock code 002929 and headquartered at the Nanning Zhongguancun Innovation Demonstration Base in Guangxi, has emerged as one of the region's earliest entrants into generative artificial intelligence and a notable provincial player in China's digital human sector. The company's virtual digital human business is built on its proprietary Quchi (曲尺) platform, an in-house AI industry model framework that serves as the technical foundation for vertical applications across smart operations and maintenance, education, agriculture, healthcare, urban governance, and new energy, with technology lead Shu Xin (舒欣) heading the research team based in Nanning. Runjian's flagship internal digital human, Run Xiaozhi (润小智), was unveiled alongside the company's AI exhibition hall in September 2024 and functions as an immersive guide that walks visitors through Runjian's AI product portfolio. On the applications side, the company has deployed government digital guides in administrative service halls, where digital humans provide large-model-powered consultation services integrated with government workflow systems, and has presented its digital human capabilities at the 2025 China-ASEAN Expo in Nanning, showcasing AI industry models, Quchi platform deployment cases, and localized digital humans for ASEAN markets that can respond in Mandarin while rendering region-appropriate attire and speech styles. In September 2025 Runjian hosted an ASEAN AI Medical Innovation Forum with Guangxi Medical University's Second Affiliated Hospital, positioning digital avatars as a means to address uneven medical resource distribution, and in April 2026 the company jointly launched a China-ASEAN Legal Consultation AI Agent with Guangxi Minzu University, featuring a multilingual digital human front end capable of voice-and-text bidirectional interaction for cross-border legal services. The company has also established a Guangzhou-based research outpost of over one hundred staff whose outputs, including an AI-plus-education product line incorporating digital human tutors, have been deployed in Malaysia as part of Runjian's broader effort to channel Chinese digital human technology into Southeast Asian markets through the ASEAN computing and smart-city infrastructure it helps build and operate.
