I'll write about 'ChangGyeongGung's glad thing and tragedy. When first I stepped in Changgyeonggung, I admired to splendid Honghwamun. So I thought Changgyeonggung has glad thing in history. Actually Changgyeonggung had glad thing. It's splendid and it held coronation and national anniversary in here. But Changgyeonggung has tragic event. Crown prince Sado dead in rice chest at here. I can't imagine that. It was painful. And Jang hee bin also dead here. I think both of them, there are political scapegoat. And also Changgyeonggung was the zoo in the Japanese colonial era and it damaged in Japanese invasion. It's so sad experience for Changgyeonggung. And I thought it's so sad. And we have to try Changgyeonggung's tragedy it can't be again. Lastly, I want to introduce Changgyeonggung to other people. Thank you for reading
