At China's border ports, X-ray vehicle scanning systems are installed in a modern checkpoint, where a large number of vehicles and goods need to pass through every day. This checkpoint is equipped with the most advanced X-ray vehicle scanning system, which can quickly and accurately detect dangerous items hidden in vehicles and cargo. One day, a truck loaded with goods was preparing to pass through this checkpoint. When the truck passed the X-ray vehicle scanning system inspection, the system issued an alarm. The security personnel immediately guided the truck aside for further inspection. They carefully scanned the truck using handheld devices and discovered a mysterious package that appeared to contain metal objects.

The security personnel immediately dismantled the package and found a pistol and a batch of ammunition. If there is no timely warning from the X-ray vehicle scanning system, this batch of dangerous goods may be brought into the country, posing a serious threat to public safety.
