Members in the visiting group were envious of the hardware equipment in the AP Training Center. However, everyone knew that a provincial training team couldn't afford them and even if they could, they couldn't afford the maintenance costs.
Just like cars, the more expensive it was, the higher the maintenance costs would be. If you bought a luxury car, you would only use the highest octane gasoline to fill its tank.
The guide introduced all the advanced equipment to the group with pride, like a guy who was showing off his fortune. Then everyone was brought to the reception room where they saw David Mills, the head of the AP Training Center.
