1. 6002, 6004, Chunsa. All of those, what do they mean?

6002 is how Yoochun ‘codes’ himself. In Korean, 6002 is pronounced as yook-cheon-i, almost identical to Yoochunnie so basically 6002 means Yoochunnie (the -ie thing is a Korean way to make the name sound more endearing). Brilliant, right? He created the ‘trademark’ when he joined Twitter with the ID ‘6002theMicky’ in 2010 (he did not stay for long though).

Similarly, 6004 is pronounced as yook-cheon-sa. And Chunsa is how we Yoochun’s fans call ourselves: Chunsa means ‘Angel’, YooCHUN’SAngel.
