  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
      ~ Manwon^^

  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 ~
      ~ Manwon^^

      • ahh no wonder the members wer e laughing at him. XD so thanks for that! and does Eddy have both of them? i wonder why he just said what he said on the show, unless it was just to be easy and what not. thanks for that!
        and yeah… i don’t know either, so it just throws me off really. and yeah the leader thing, have no clue whatsoever.

        and you’re welcome and thanks for double checking and not wanting to be inaccurate and such either. thanks again!! =]

      • your comments are just a joy to read ~ we will continue to check out the leader situation in this group ~ and update as best as we can ~ please continue to send us any videos you may find with info in the future ~

        I didn’t have a lot of time to look into Eddy’s names yesterday either, but I think I will end up just listing both names on his profile ~

        Thank you again for just the wonderful responses, and sending us the videos!

      • you are super welcome!! and thanks for helping me out as well and yeah if i ever do, i will surely send them!! it’s always a joy watching these boys. lol they are so entertaining. ahaha. just hope to see them in more stuff later on~ =]

  5. To those who are still unaware, JJCC’s fancafe staff announced the official JJCC fandom name to be ‘Diamond’ earlier this morning. However, this fandom name is already being used by another Kpop group called ‘Pure Boy/순정소년’. I personally have not heard of them before and they don’t seem to be extremely popular, but that’s not to say that we as JJCC fans should disrespect them by using the same name as their fans. (Above photos show tweets from their Twitter directly calling their fans “All our Diamond fans”.)
    JJCC fans, how do you feel about the announced fandom name after hearing about this?

    • Pure Boy is a rebranding of the group Pure who debuted last year, Pure Boy is supposed redebut sometime this year. As far as I know Pure Boy does not have an official Fanclub name yet, unless Diamond was the original Pure’s fanclub name and Pure Boy will continue using. I will look into it though.

      On a happier side, its super exciting that JJCC fans have an official fanclub name.~James

      • Okay so our name is officially KEYS now! The fanclub name is keys. KEYS, KEYS, KEYS, KEYS????!! What happened it was like a total down grade from a diamond to a key?!?! Whatever atleast we have a name now🙈 please look further on this, I already have but it’s still not getting to me. Oh and pls put it up on the N/A for the fanclub name. Thnx I don’t even know what to say about it……

  6. [Mak’s FB Update] “Such wonderful fans in Busan <3" ct: … Please support JJCC International Fanclub! …. fancafe staff announced the official JJCC fandom name to be 'Diamond' earlier this morning.——-

  7. Haha, I celebrated his birthday in my phone:) awe I’m sorry you missed it I should’ve commented a notice! The members have him a cake and they celebrated it with themselves! There’s post on twitter I think on simba’s profile.

    • Yes it was. Prince Mak posted on twitter saying happy birthday to the baby. xD I had no internet yesterday so I barely saw it since he posted it before my internet went out D: I couldn’t do anything T-T

      • OMG! are u like a really big fan of JJCC? Cuz I see a lot of your comments here…… Just asking cuz I am even tho they only have 1 song out. Aaggh can’t wait for their next song coming soon! But yah and may 24th is prince mak’s birthday so…… U know….

      • Haha, Yes I am! I bought their autographed CD for their meet and greet. They read my meet and greet message I sent them. and E.co gave me three hearts and made me say that I love him and he said he loved me too. He isn’t my bias, but I love alll members. and I completely died when eddy said my name and they were reading my message ❤ They compared heights because of me too 😀 ❤

  8. I don’t think Simba is 184cm.
    Because E.co is 186cm and in all videos and pictures of them, Simba is visibly taller than E.co by quite a bit. He’s often more seen as a giant. A lot of people have been assuming a typo due to the disbelief of his height being so tall but I’ve heard that maybe 194cm is the more accurate height. I’m not sure myself, but Simba looks to be far taller than 184cm.

    • I would have agreed with you once before, but one of our followers (Misty Allen) posted a video in the comments, and in the video Simba and E.Co address the height difference, and show us themselves that they are really close to the same height. You can follow the link here: http://mwave.interest.me/mnettv/videodetail.m?searchVideoDetailVO.clip_id=160564 and see for yourself^^
      Plus the information we have on our page comes straight from the official profiles typed up on their daum cafe. We are constantly striving to bring you only the most accurate information ~ thank you though, because we had wondered the same thing for awhile there^^

    • My personal theory is that when they do photo shoots and different official functions the directors and photographers place the members in a way that makes Simba appear taller than everyone else, because he is the leader. Changmin from DBSK always had to crouch down or squat slightly so that he never appeared taller than Yunho who was the leader. Height is can be really important in Korea so it may be that people would believe that Simba was a less effective leader because he is shorter than E.Co even if it is only by 2cm. ~James

  9. i just fall in love with them specially eddy his voice is different and i like it hope great sucess in there lifes and keep up the good work fighting!

  10. Hey! OMG, I love their song “at first” it’s my ringtone for everything! I remember one of their interviews/ talk they said that they are planning to have their next song/ album by either the end of July or the end of August! Ahhh can’t wait!! I wish they have the official name of their fanclub already! This is a fan from LA California, shout out to all the other fans from here!!!! Luv them!!!!

  11. When I first heard “At First” I thought that it was pretty good, but that’s as far as my love for JJCC went. Then I just watched this episode of “Let’s Go! Dream Team 2” which had Simba in it, and now I want to hear more of their music and learn more about him XD If you watch the video, you can also see the other JJCC members at times, but you mostly see Simba, who did freaking amazing throughout the entire episode 🙂

      • lol I’m really glad that someone else found this episode enjoyable, too. I wasn’t looking forward to watching it because I didn’t know any of the rookies, but I’m really glad that I did end up watching the whole thing because now I love Simba!! XD

    • Well, KBS is evil, and has blocked this video in Korea, so i can’t watch it. Guess i’ll have to wait til im stateside in 3 months to watch it. ~James

      • Ahh! I’m sorry! I didn’t know that you were in Korea, and I also didn’t know that KBS blocked their videos there :/

      • I didn’t know they blocked them either. Guess they don’t think about us poor foreigners who don’t have cable here. at least I’ll be able to watch it next time I’m home in the states.

  12. I just watched their meet and greet on Mwave and they read my message!!!! even though I think it was a bit creepy..i feel horrible for it. 😦 but I got 3 hearts from E.co and he added a part at the end of my message, saying “oppa, saranghae” with a heart and than he pointed at himself than me than did another heart ❤ but I mentioned how is it that E.co is taller than SimBa when he doesnt look like it, he proved that he is taller, but it depends on the angle and such. their height is almost the same, but E.co is just barely taller than SimBa. I am so happy!! xD
    Here is the video! I can't stop watching it…lol.

    • Haha, That’s great that they read your message! I just went and found the part where the read your letter! It was a fun letter ~ and how exciting is it that they read your letter!?! I am super excited about it! And that I know you, so I know who it is that they are talking to >.< hahaha
      Anyways, not only was it fun to watch, but we learned something new about their height!
      ~ Manwon^^
      p.s. every time I see you've commented on here I am happy, you are so pleasant and fun to chat back and forth with about everything ~

      • Aww, thanks!!! hehe. I wish I could go back in time and fix it, because I sent that message not long after their debut, when the meet and greet appeared. So many things happened since then. xD I just love how I was one out of like 2-3 people that received hearts. I think I was the only one that received it from E.co and of course they did it for pictures too, but still. xD apparently I love E.co Oppa. He said so. xD Do you have facebook or skype or something? I enjoy talking to you too x3 hehe. but I completely died. especially when they started reading my letter and the video paused and I was like HDIOFNHIOFND NOOO. so I refreshed while my friend was watching it and she was like OMG prince mak keeps laughing at it and E.co did hearts and I was like T____T. so I finally watched all of the message when it was uploaded. I was soo happy and crying. xDD

    • That is what Manwon^^ and I are kind of guessing too, but we do go off of the official profiles posted on the groups Daum cafe which says that Simba is shorter than E.Co (obviously not true when you look at them) but until otherwise stateded we will be leaving the information as we have it. ~James

    • They said they are going to be working on their new album, they hope next week that they will start working on their album that they are hoping will be released in July. 🙂 They said that on Sound K’s star date~

    • We have seen that site and the information is the same as what they have posted on their official fan cafe. So our profiles reflect that. we do not post fun facts for any group purely because we know some groups really well and others hardly at all, as well as only wanting to post information that we know is true. Thanks for sharing the link again, This way fans do have to go through 100 comments to find the lingk

    • That’s the one from their cafe too and the info that has mainly been used. But it does have their real names listed on that page, lols. xD it’s been posted before, when it first came out~ 🙂

    • hahaha ~ I think you may be right, unless Simba is wearing some really intense shoe lifts ~ I think that person wrote those heights because something is off on the profiles from the official daum cafe ~ it does say that Simba is 184cm on the daum cafe – all the info we have on our profiles are from the official daum cafe, so I think that person was pointing out the weirdness of the daum profiles

  13. I know this might not be a reliable source, but there was this article in korean that states that Eddie is 24, E.co is 27, SimBa is 22, and San cheong is 21~ I know it shouldn’t be trusted yet, but I sure hope this is the ages, since they are all barely older than me 😀 I repeatt, this is possibly not a good source, so don’t completely believe it. There is just a chance that it is right. xD

      • Awesome ~ Thank you for that^^ I was checking their daum cafe when you first sent the link so it’s great to know the info is true ~ we will put up the ages! And get them in the correct age order ~

      • Yayy~ I am so happy we finally know all the ages!!!!!! It was driving me nuts, haha. xD

      • I know! I was dying to know how old they all were too! I am surprised that Simba is one of the younger members, but maybe that’s just because he is so tall hahaha ~ Manwon^^

      • San cheong was born in 92 and Simba was born in 91. xD Since it said their birthday is 21 and 22 since their birthday haven’t passed yet~ Otherwise you have that SimBa is 21 and san cheong is 20 xD

      • Haha, it’s fine! It was only one year off~ But I only know because I am 21, and They are close to my age. Plus, Eddy is my brothers age too. xD

      • wait but that doesn’t make sense for Eddy to be born in 1989…
        because if he stated he was 21 on that chef show, before his birthday that year…then he should be turning 24 or 22 this year ~ i’m guessing during the interview they just told their years so they assumed he was already 24. so i think he’s actually a 1990er not a 1989er ~
        same probably goes for the other members. so SanCheong = 1993 or …Simba = 1992…E.co = 1987
        that’s the only way Eddy saying he’s 21 in 2012 (most likely filmed b4 july 7th, bc if it was after that would mean Sancheong is currently 19 turning 20, which is unlikely since all of JJCC are in their 20s)
        but yeah, hopefully an official post or video will be made directly by JJCC soon though!

      • You could be correct about the ages, but after discussing it with Manwon^^ we have made some decisions.

        We know that the information in the article is correct and that Eddy either currently is or will be 24 this year, because the group would not post/retweet wrong or incorrect information.

        Assumption 1: All ages are international age, because we know that E.Co’s birth year is 87 from his official profile from when he was in J.Rich, making E.Co 27 already.
        Assumption 2: The members gave their current ages, because most people when asked about ages do not say their birth year. They either say their
