Jin was born to a poor family in the Liaoning province, China. At the age of 5 he was sent off to do child labor as his parents was in debt. He never saw his parents after that. He was forced to do a variety of different kinds of manual work and was poorly fed. One time when he was 7 he stole a cigarette and smoked it as he had seen the adults do it. He was treated poorly and had no hope for his future. He thought he would either die from starvation or that he would be worked to death. He was shorter and skinnier than the other kids he worked with.
The supervisors who ran this operation of child labor turned out to be in debt to a man called "Ling Wong" and he so happened to have been in need of some workers for his soon to be Chicken Shop in South Zagoria. Every kid was happy as it was an opportunity of freedom and change. Since all the kids wanted to work at the shop in South Zagoria, the supervisors held a draw. Each kid was handed a slip of paper with a number in it. ONLY one kid was going to be picked as they could not afford to lose many workers for free. The number that was picked out was 11 and this so happened to be Jin's. A week later he was given a fresh batch of clothes and was sent to South Zagoria with one of the supervisors to meet with Ling Wong. On the journey over it was Jin's 13th birthday. He asked for a cigarette as a present as it wasn't much and he believed it to be acceptable. Fortunately the supervisor thought so too and gave him a fag and a light.
The supervisor introduced Jin to Mr. Wong and was soon on his way out the door. Mr. Wong showed Jin around the shop and the duties he would have. He also thought him how to cook. In the short while he also began to teach him some english as it was what a lot of people could speak and it would benefit Jin in the future. Mr. Wong was kind to Jin and he appreciated it and put all his effort into the work.
Once the outbreak occurred Mr. Wong continued to have high hopes and taught Jin more english so he could communicate with the populous that had survived. Jin is actively helping Mr. Wong achieve his dream of re-opening a new Chicken Shop and making it successful. He follows Mr. Wong's lead and has integrated himself into a group known as DISTRICT.
