Jin Zaijun, Chinese-American, born in 1999.
After joining produce101, I like to hang out with my brothers.
Almighty and good at changing the atmosphere.
Participated in JYP auditions in 2010, and was spotted by Bang Si Hyuk together with Jung Hoseok, and later trained as a bulletproof preparatory student.
In 2013, he was not selected because he was too young, but he chose to stay and continue practicing. During this period, he often appeared in Bangtan's backup dance group. The relationship with Bangtan is extremely good.
