Hello. ¼ºÇÐ :-)

There are many information in your essay.

It was so impressive for me while reading it.

In particular, I liked the explanation for Ondol.

Heungseon Daewongun ruled Joseon for about 10 years in the Unhyeongung Palace.

Unhyeongung Palace is a very important remains in the late Joseon history.

So, the Unhyeongung palace is designated as Historic Site No. 257 of Seoul.

I look forward to your next essay.

Bye~
