Original and 8K masterpiece，Showcase the best quality and ultra-detailed illustrations。There is a boy in the picture，It's an engineer，Black eyes and short black hair，Wears blue half-sleeves。His face is rounded，Repairing a circuit board on a messy desk。There are also soldering irons and welding tools，As well as quadcopter UAVs under repair。This drone is a DJI product。The screen also shows the circuit board and some electronic hardware。The boy's expression is focused and his body appears halfway，He lowered his head and concentrated on his work，Looks very serious、having fun。
