I graduated from Dong-a university as a chemical engineer. Unlike others, I speak English, Chinese, and a little bit of Spanish. I never stopped studying languages because I love to go abroad. For example, when I was in the army, I volunteered to dispatch to South Sudan. I was quite confident with my English ability at that time. If I were not good at it, I would not have thought of going to Sudan at all. I have many experiences giving a presentation in front of my colleagues. Having confidence is my great strength.
