Don't confuse the south Bronx with the north Bronx kicko
Anyway what's the story between these two?
Jin was in a club at the peak of his "run". Disrespected one of China Mac's dudes wives (dude was locked up at the time). Mac pressed him in the bathroom, Jin's homeboy pulled a knife, Mac had a gun and pulled it. It jammed when he had a head shot. Jin and dude ran as soon as he pulled it, so when Mac tried to shoot again he shot Jin's homeboy in the back.
Jin told police everything. Mac was on the run for a year and didn't get caught until he tried to cross over into Canada. After he got caught, Mac served like ten years.
Before he got out, Jin wrote him a letter kinda putting it all out there. He apologized for his actions that lead to the situation, saying he was a different person now that he found religion and was just over in China preaching the gospel. Basically wanted to know if Mac was still going to have it out for him (the gang that Mac runs with has links in China too so Jin couldn't really breathe easily just because he's mostly abroad), and Mac said he told him he wasn't out for revenge on him because Jin wasn't running the streets. He was a civilian dude who did what civilians do.

Jin himself would tell you that lol
