Fa was nearly going insane. He was a small-time local thug, lazing around all day with nothing to do. As a petty ruffian of his rank, he couldn't compare with the big shots. He had no properties of his own and only three or four underlings.
Most of his income came from several low-tier high schools and colleges in the vicinity.
Fa's path to wealth wasn't exactly about collecting protection money from students. Broadly speaking, he took money to solve other people's problems. Specifically, when some students got bullied and couldn't fight back, they had no choice but to spend money to hire some muscle, and that's where Fa and his gang came in as the hired fists.
Students these days weren't eating coarse grains and pickles anymore, especially those from low-tier high schools and colleges, who were often rich kids. They wouldn't blink an eye paying a commission ranging from thousands to tens of thousands.
