Hello AnnA~

I'm glad to read your essay.
National Museum of Korea have a lot of cultural property.
It is a great pleasure to see our treasures at the museum.

I agree that Goryeo's Printing technique is very great.

The contents of textbook is important,

but you need to say your feeling little bit more.

These days weather is really cold.
Be careful not to catch a cold.
Have a good day. :D
