Today I've been changgyeong Palace. Seongjong built Changgyeong Palace for his mother and grandmother. There is Honghwamun, the main gate of Changgyeong Palace. Okcheongyo is a stone bridges between a main gate and main palaces. the Myeongjeongjeon place for official event. the place for the queens are Gyeongchunjean, the place for sleeping is Hwangyeongjeon. sungmundang. is a place for academic discussion, Haminjeong that the King Yeongjo met the successful students. The Dancheong is the decoration. there is red, yellow, green, black and white color. Red means fire, yellow means earth, green means tree or wood, black means water and white means metal. I think that king Seongjong is very good son because he built Changgyeong Palace for his mother and grand mother.
