I Asked You to Repair the Computer, but Not the Photolithography Machine!

Is your graduation thesis gone? Is the national treasure instrument broken? Even the fire control system of the armed helicopter failed? Don't panic! Feel free to visit the "Everything Can Be Repaired" store in College Town. The boss, Liu Yang, holds an eight-year-old soldering iron and relies on the All Things Can Repair system. No matter whether you have a physically fused motherboard or a lost antique from foreign countries, it can be done in three seconds and costs ten yuan. Years later, when the 0.5Nm lithography machine was delivered to him, Liu Yang just pointed at the faded QR code. "New here? Scan the QR code and it's ten yuan."
