It's not a lie, it was so easy to understand. I'm a Python backend developer, so I didn't study anything except Java a long time ago, but I listened to Mr. Kim Young-han's lecture and it was so good because he explained it in an easy-to-understand way. I think I'll become a total fan! I understand why people say Mr. Kim Young-han's lecture is the best. He picks out the best parts and uses great analogies, so it's so easy to understand.
