Lady Jang, the mother of king Gyeongjong was killed. She had to drink up poison.

 Crown Prince Sado, the father of Jeongjo was dead because of his dad's mistake. His father, Jeongjo thought that Sado was crazy.

 Last happening is related to Japan. Japan changed the palace to a zoo. So many normal people got into the palace and laughed at this.

 In Changgyeong palace, there are so many buildings that i can not memorize. I was always interested in Lady Jang's dead. And i could know many details of her. She was actually just normal lady at first. There were many interesting things at there. Especially i liked the carvings that protect the palace such as Japsang and Hech
