I'm going to explain about the Myeong Jeong Jeon (명정전) and Il Wol Oh Bong Do (일월오봉도) which is inside it. The Myeong Jeong Jeon is the main building of Chang Kyeong Gung palace. It is in the outer palace. It was the place where the king held morning assemblies, coronations, royal, weddings, and greeted merchants from China. In front of Myeong Jeong Jeon, there are a lot of Pum Gye Seok (품계석). It represents how high that official is. If they are in the front, they mean that they are very high. Inside the Myeong Jeong Jeon, and behind the throne, there is a painting called the Il Wol Oh Bong Do (일월오봉도). It represents the power of the king. The sun represents the king, the moon represent the queen, the pine trees represent the loyal officials, the 5 mountains represent s the territory of Joseon. And lastly, the water represents the normal people.
