Lao Pi is part of the management in a state-owned enterprise. Lao Pi is a nickname rather than a real name, kind of like a pen name. After crawling and rolling through the enterprise for so many years, he's become quite adept at speaking and handling things, and his flattery made Wang Fan feel quite embarrassed.
However, Wang Fan has always been reluctant to take free things; he insists on paying.
Lao Pi insists on giving it for free, since it's not really worth much anyway.
In the end, seeing that Wang Fan's attitude was particularly firm, Lao Pi didn't want to waste everyone's time on this matter and sold it to Wang Fan at the market price of 20 yuan per jin.
No need to actually pay, just offset it with the purchase money. The five jin were directly offset by 100 yuan, which is considered waste utilization.
As the two chatted, the fish skin was already roasted, and the rich aroma spread to every corner of the boat, making everyone on board swallow their saliva involuntarily.
