Liu De was a nouveau riche, the kind struck by dumb luck.
He had no status, no background, no connections.
At the time, to prevent others from oppressing him too severely, he simply made friends with the leader of the hoodlums on that street.
While everyone else dreaded paying protection money, grudgingly parting with each payment after much hesitation, and each time it took Iron Head smashing something in their shops for them to cough up the money,
Liu De was not short on cash then, and he was especially generous with his money, not only paying the protection fee but also giving extra.
After a while, Iron Head got on friendly terms with Liu De.
In Liu De's shop, whenever troublemakers appeared, he would call Iron Head over to help intimidate them.
This time, he hadn't expected anyone to have the nerve to chase them down to the factory to cause trouble, or else he would have had Iron Head come over to support the scene earlier.
So Liu De was quite confident in Iron Head.
