Gongchan, who is currently a maknae and the visual in the group B1A4, showed his variety skills on 'Hello Baby'.
'B1A4's Hello Baby' airing on August 1st on KBS joy, had 'Getting to know Seoul' as their first project. It questioned their knowledge on 'Seoul (or city) people', and quizzed 'Country idol' B1A4 how much they knew about Seoul.
Gongchan showed variety skills during the entire broadcast and recieved a compliment from the special MC/Comedian, Jang Donghyuk that he was a "variety genius". During one of the interviews, Gongchan was asked "If you graded your own variety skills?" and he proudly answered "80 out of a 100", which made people watch the show with expectation.
Meanwhile, the members of B1A4 made the PD shocked from their answer of the question, "Who is Seoul's Mascot?" (the right answer is Haechi). They answered 'Hodollie' (the 24th Olympic mascot at the year of 1988).
Depending on the result of the quiz, the 2 members with the highest scores were a team, and the 3 members with the lowest scores were a team, and they went on two very different tours (one horrible and one good) of Seoul with their baby.
