On the evening of June 27, at Tangshan Music Valley in Nanjing, the final stop of Yan Renzhong’s “MOMENTⁿ” Concert Tour officially began. From the gentle performance of Slowly to the heartfelt rendition of Good Night, more than twenty hit songs were performed one after another. Over 30,000 audience members sang along, igniting the entire summer night with enthusiasm.
As night fell, the real surprise appeared in the sky. Thousands of drones took off simultaneously, creating two precisely coordinated formation flights that visualized the emotions of the music. The “director” behind this spectacular drone performance was Nanjing AllXF Robotics Technology Co., Ltd., located in Qilin Science and Technology Innovation Park, Jiangning District, Nanjing.
Powered by its self-developed S3 Swarm System, AllXF once again delivered a stunning performance in a large-scale cultural tourism and live entertainment event, perfectly blending the passion of music, the power of technology, and the gentle charm of Nanjing into the night sky above Tangshan.
This drone performance was not simply a light show, but an “aerial accompaniment” deeply integrated into the narrative of the concert. Based on the emotional progression of Yan Renzhong’s songs, the AllXF technical team carefully planned two themed drone displays.
At 8:50 PM, as the prelude of I Will Be by Your Side began, the drones transformed into a giant “MOMENTⁿ” logo and the artist’s exclusive emblem. The iconic “Renzhong” and “Zhongren” IP characters appeared in the night sky, followed by the message “I Will Always Be by Your Side,” suspended high above the audience and resonating with the music.
At 9:30 PM, as the prelude of Good Night flowed through the venue, a “shooting star” streaked across the sky, followed by the words “Good Night” and “Good Night, Nanjing,” creating a touching moment that left all 30,000 spectators deeply moved.
An AllXF team member said, “What we create is more than just drone flights. We use technology to express the emotions of music, the sentiments of a city, and the passion of its fans. We hope every performance becomes an irreplaceable moment in the sky that remains in the audience’s memories.”
This was not the first time AllXF had appeared at a large-scale cultural tourism and entertainment event. From the Nanjing Cultural Tourism Festival and the Jiangsu Football League to Tangshan Music Valley, the company has carried out more than 2,000 drone performances across China, including more than 60 performances in Jiangsu Province alone.
Behind these impressive figures lies AllXF’s continuous commitment to independent research and development as its core competitive strength.
Founded in 2019, AllXF is built upon three core technologies: artificial intelligence, automatic control, and navigation & guidance. The company continues to focus on cutting-edge fields such as permanent magnet synchronous motor (PMSM) control and integrated sensor intelligent gimbal control. Its self-developed S3 Swarm System is based on an autonomous swarm architecture and covers hardware, software, and service systems. All core technologies are independently developed, procured, and controlled by the company, while supporting continuous iterative upgrades.
During this performance, despite challenging conditions—including a ground temperature of 32°C (89.6°F), muddy terrain at Tangshan Music Valley, and a complex signal environment—the S3 Swarm System demonstrated outstanding adaptability to extreme environments and strong anti-interference capability. Combined with the precise timing and coordination of the drone pilot team, both drone shows were completed flawlessly, exactly on schedule.
In terms of its technology roadmap, AllXF is evolving from comprehensive in-house development toward open collaboration. The company is gradually working with partners in Nanjing and Jiangsu Province on collaborative development, application, and iterative improvement. At the same time, AllXF has established a rapid closed-loop iteration mechanism. By leveraging on-site operational feedback and audience data, the company can complete the entire process—from problem identification to system optimization—within just a few days, significantly faster than the iteration cycle of traditional industrial systems.
AllXF established its operations in Qilin Science and Technology Innovation Park, Jiangning District, Nanjing, in 2021. Its core team consists of senior experts with extensive experience in robotics research and development and product design, and has accumulated more than 100 core intellectual property rights. Thanks to its outstanding innovation capabilities, AllXF has received numerous prestigious awards, including the First Prize of the National Defense Science and Technology Award, the Gold Medal at the Geneva International Exhibition of Inventions, and the Outstanding System Design Award at the International Control Robot Competition. The company has also obtained multiple internationally recognized technical certifications, ensuring excellent product stability and compatibility in complex global application scenarios.
From 2024 to the present, AllXF has been invited to participate in the Shenzhen International UAV Expo for three consecutive years, where it showcased products from its D Series, Z Series, and S Series, as well as its new 4K full-featured micro gimbal camera. These products have been well received by customers from both domestic and international markets. The company’s rapid growth has also benefited from the comprehensive support provided by the innovation park.
The performance at Tangshan Music Valley is a typical example of AllXF integrating its drone performance technology system into cultural tourism scenarios. Against the backdrop of the low-altitude economy being elevated to a national development strategy, drone performances are evolving from simple visual attractions into a standard narrative element of large-scale live entertainment events.
As the core destination of a National Tourist Resort, Tangshan Music Valley continues to build a new landmark for Nanjing’s nighttime economy through the integration of music, technology, and ecology. The perfect combination of this concert and the drone performance was not only an impressive audiovisual spectacle, but also a vivid demonstration of Nanjing’s innovative “performance + technology” model for cultural tourism development.
Based on Nanjing’s rich cultural tourism resources, AllXF will continue to expand the application of unmanned system technologies in live entertainment, public services, and various vertical industries, guided by its vision of “Making Nanjing More Beautiful with AllXF.”
Driven by technological innovation and supported by an open collaborative ecosystem, AllXF will continue to foster business growth, bring together the strengths of its partners, and contribute to the high-quality development of the low-altitude economy.
