"You little brat, you're from the police station, but I'm from the Police Bureau. Give me back the crank handle, and do it quickly!"
"I'm warning you one more time, don't move!"
"Are you out of your mind? I told you not to move."
"Try and move, I dare you to get off the boat, I'll throw this crank handle into the river!"
A single-cylinder diesel engine requires a vigorous turn of the crank handle to start if it isn't equipped with a starter motor.
If the little brat down there throws the crank handle into the river, the diesel engine won't start, and the boat won't move. For a moment, the boat owner was dumbstruck.
Huang Jiangsheng didn't know what Han Yu suspected, but worried that Han Yu would be at a disadvantage, hurriedly said, "Xiao Han really is with the police, so if he tells you not to move, don't move, or you'll be facing legal trouble!"
Shifty looking and clearly not a good sort.
From the accent, he's not a local either.
