The old phrase "jultakdongshi“ means that
something is accomplished only when the inside and outside work together.
 

A chick must come out of its shell to come out into the world.
A chick cannot remove its shell on its own and needs the help of the mother hen.
When the two work together, the chick enters the world.

Like "jultakdongshi," the BI of Seoul Campus Town signifies the success (hatching) of startups through cooperation
