The client needed to operate normally during the day, so we came after hours. Several staff worked in parallel and finished testing and cleanup before closing.
A foreign-company offices client working in Gubei had devices failing and holding up progress. We visited by appointment and handled them in groups, restoring normal use the same day and logging the devices into a table.
A cross-border e-commerce client in Xianxia had a device go down suddenly. We judged the fault direction by phone, and our technician brought matching parts and completed repair and testing the same day.
The client used to call only when something broke, and faults kept recurring. After asset records and scheduled inspections, the number of service calls dropped noticeably.
The client moved into a new office in Xianxia, with devices and cabling to re-organize. We tested and numbered each device and delivered an equipment list at handover.
The same problem had been handled twice elsewhere without a fix. We re-diagnosed to find the real cause, and after repair it stayed stable for a week of observation.
