For the second visit to Changdeokgung Palace, I had a slight regret about the secret garden. I only took the time to look at the flowers, thinking that Houyuan is the lotus pond in the door. Who knows when I go back to see the information and discovers that there is still a hole in it. When modern tourists think that it is the back garden, it is actually a natural forest. The royal buildings are distributed in the mountains, have libraries, experience civilian life, and enjoy the summer and other functions. The midday sun brought plenty of sunshine, and in the mountains, the top light turned into light and shadow. Light and shadow take us to walk a period of time. I lifted the skirt and smashed it on the staggered stone road.
