Every positive review is the greatest endorsement of our service
My laptop got water damage at dawn, and the technician arrived with drying equipment and saved my data in 2 hours! Professional gear and fast response really matter.
Apple Support quoted CNY 7,000 to replace the motherboard - Fengniu Tech fixed it for CNY 1,800, with a 180-day warranty!
I compared several buyback platforms - Fengniu Tech offered CNY 200 more than one of them and paid me on the spot!
We have built a standardized evaluation system for idle digital devices for both businesses and individuals, with open and transparent buyback pricing. We also offer flexible rental of high-performance office computers and test equipment for startups and enterprises, lowering the barrier of heavy capital spending.
We focus on sudden hardware and software failures in hard drives, USB flash drives, phones and other storage media. Through low-level sector cloning, fragment-level extraction and logical reassembly, we recover lost critical technical documents and data while keeping your privacy strictly confidential.
We break down technical barriers for non-expert users and small and mid-sized business teams. We provide large language model API integration, local private model setup (Ollama), custom AI workflow design (COZE), and deployment plus training for productivity tools such as Cursor and Claude.
We are a walk-in and on-site repair shop in Zhengzhou, Henan. We serve international students and residents in the city, and we also take in board-level work from repair shops outside Zhengzhou and from overseas.
