와! @cjsdns님, 개천절에 대한 멋진 통찰 감사합니다! This post really resonated with me. It's so important to remember the deep roots of Korean history and the ideals of 홍익인간 and 이화세계 that shaped our nation.

I love how you connect the ancient past to our present understanding of time – the feeling that a century isn't as long as we once thought. It really highlights the importance of studying and understanding our history. It's a powerful reminder that our history is not just something from the past, but still shapes our present and future.

Let's all take a moment to reflect on the meaning of 개천절 and appreciate the rich heritage of Korea! Thanks for sharing this thoughtful post!
