On January 17, 2019, the Third National Intelligent Manufacturing Innovation and Entrepreneurship Competition concluded in Hechuan District, Chongqing. The competition was jointly hosted by the China Electronics and Information Industry Development, the China Industrial Internet Development Alliance, the Chongqing Municipal Commission of Economy and Information Technology, and the People's Government of Hechuan District, Chongqing. It aimed to promote the implementation of technological projects, gather innovative resources, and create a cross-industry national platform for financing, investment attraction, and talent recruitment, fully boosting China's technological innovation, intelligent manufacturing, and other emerging industries to new heights.

Since its launch, the competition has attracted widespread participation from intelligent manufacturing project teams both domestically and internationally. Over 2,000 projects registered through five (East China, South China, North China, Southwest China, and North America) and three industry-specific tracks (biomedical, IoT applications, and artificial intelligence). More than 70 experts ***ed 310 projects for the preliminary round. After over two months of roadshow reviews, industry expert screenings, and ***uations by investment professionals, 24 companies advanced to the finals, where competition was fierce. The finals involved live roadshows, project Q&A sessions, expert scoring, and collective voting. Qingwen Technology's "Doctor of Directional Listening" received unanimous praise from the authoritative judges and sparked strong interest among the audience and public judges. Ultimately, the "Doctor of Directional Listening" project won first place with the highest score.

Qingwen Technology's "Doctor of Directional Listening" is an ultrasonic directional sound device. Its key feature is directional sound propagation—like a flashlight beam for sound—allowing audio to be controlled and played only within a specified area. People within the target zone can listen to their respective audio without interference. To date, this ultrasonic directional sound device has been deployed in exhibition halls and supermarkets in cities such as Beijing, Xi'an, and Ningbo. In retail settings, installing the "Doctor of Directional Listening" at store entrances enables promotional messaging without disturbing nearby areas; in product display zones, it serves as a shopping guide; and at checkout counters, it broadcasts discount promotions while improving staff efficiency and store revenue. Currently, hundreds of convenience stores in Shanghai and Beijing have successfully installed the "Doctor of Directional Listening" guidance system. In museums and art galleries, the device allows directional narration of exclusive stories behind each exhibit, ensuring even closely spaced exhibits remain free of audio interference, providing visitors with an immersive and personalized listening experience. The "Doctor of Directional Listening" can already be found in venues such as the National Museum of China, Military Museum, and Overseas Chinese History Museum. We believe that in the near future, our products will benefit even more people!
