(English) While working as a derivatives dealer at a financial institute, it suddenly hit Kim Seongho that writing was his calling, so he dived into the publishing industry. Rote learning for the university entrance examination was at its peak when he was a student. Field training was out of the question, asking questions irrelevant to examinations in science or world history class was impossible and even if questions were asked, the teachers never answered. As a result, science and world history became his most hated subjects. He felt sorry about this for a long time and that's why he started to write a text like this. He started writing children’s books and has been working as a children’s book writer so far. The books written by Kim include Flower of Wind and Sun, Salt, Uncomfortable Truth About Faith, Religion, Ballot, Power of a Piece of Paper, and Two-Faced Energy: Nuclear Power Energy.
