  1. I did a little analysis to find out their birth year on the article u linked, and based on the article, e.co was 27, eddy 24, simba 22, and sancheong 21.
    “에디(오종석·24)는 10년간 트레이닝을 받은 ‘청룽 키즈’다. 심바(김영진·22)와 이코(하준영·27)는 국내외 유명 패션쇼의 런웨이를 누빈 모델 출신이다. 막내 산청(최하돈·21)은 한양대 연극영화과 재학 중이다. 프린스맥(헨리 프린스 맥)은 중국의 유명 서바이벌 오디션 프로그램 우승자 출신이다.”
    See those numbers there?
    So, based e.co’s birth year, he is already 27 (international age) when the article was posted, which is on april 12, 2014, while the other members hadnt had their birthdays yet. And bcos this is a korean article, i believe they’re using korean age but werent aware that e.co has turned 28 (korean age) by the time they published it. Therefore, my assumption is, in that article, e.co was 27 (korean age) before he had his birthday in march. Moving on.. e.co is 3 years older than eddy, means eddy is a 90liner. Simba is 2 years younger than eddy, hence he’s a 92liner, and sancheong is 93liner since he’s a year younger than simba.
    However, this is just my assumption and result from my analysis. It can be wrong but that is what i believe for now haha

    • In Korea everyone becomes one year older on January 1st, so E.Co would have already been 28 Korean age at the time of the interview ~ And figuring Eddy’s age is really difficult because of his interview for the cooking program he did before joining JJCC ~ James and I have been trying to figure out their birth years for almost a whole year now, and the math just never seems to add up right for Eddy, his cooking program, and the articles we read with his age in them…Every time I do the math according to the article Eddy would be born in 89, with Simba being 91 and Sancheong being 92…so we leave the JJCC ages the way they are…it’s very frustrating to not know – and I have gone as far as emailing the daum cafe, and privately messaging Simba on facebook asking if the birth years of the members will ever be released, or if they could let us know their birth years. I have heard nothing back (as I expected)…so for now we have to just leave it as is XD

  2. Simba is not the leader. San Cheong is. They did it to prevent him from slacking off and becoming lazy. Watch them on Pops In Seoul and After School Club to confirm.

  3. Who’s the leader of JJCC? I’ve seen some sites saying it’s simba, others says it’s san cheong (which I think is pretty weird to have the maknae as the leader haha). So can someone confirm who’s the leader?

    • JJCC originally had made Simba the leader, they later announced that they made San Cheong the leader so he would act more responsible – they have not made an announcement since announcing San Cheong becoming the leader changing the leader. James and I are always keeping up to date with JJCC so if they ever announce anything new regarding this we’ll update the page, but the last news about the leader made San Cheong the official leader of JJCC

  4. alright, some info of the boys!! just wanna mention that Eddy’s full name from what i saw of a video, them on K-Populous, is “Edward Young Oh”. o.0 and Sancheong is no longer the leader, but Simba is. [not sure how that is possible as in ASC, Sanchong was still considered as a leader though] and E.Co mentions his surname is “Sa” and when saying Sa E.Co it’s like “psycho” but i’m not sure if it is or not from the k-populous video.

    but here’s the 2 videos:



    thanks a lot for the information though!! =]

    • So I started watching the videos, but I also double checked the profile information provided by JJCC on their official fan cafe and the real names that we have are the real names as provided by the group by their company and group, So I don’t know what to make about the videos, I will talk it over with Manwon^^ and we will make changes as necessary

      • alright thanks! =] and yeah i don’t know what to make either, since it totally threw me off. XD and i can’t read much about their official fancafe anyways, so i trust you guys. =]

    • Thank you for sending the info ~ E.Co was making a joke when he talked about “Sa and Psycho”, Eddy has both a Korean name and an English name, and I don’t know when they recorded either of these episodes, so timing wise SanCheong is most likely still the leader

      Until we get anything more conclusive from their official profiles – which haven’t been updated on their daum cafe, I don’t want to change anything regarding leader ~

      We do thank you for sending the videos ~
