Today I went to Seoul museum of history. There I looked about the history of Seoul. We looked it from 1392 when Lee Seoung Gae established Joseon dynasty. And then he built the shrines and the five palaces. And to protect Hanyang, he built the four main gates. Seung Rae Mun, Sukjungmun, Heunginjimun, and Doneumun. And the reason that Lee Seung Gae picked Hanyang as the capital is because of the central location and the good view and naturue. Also there was hopae and the Epic poem. The Epic Poem was the first book written in Korean, and the Hopae was like a identification card, so if we show them to the guards, we can pass the doors safely. I had a great time in the Seoul museum of history.
