Last month I visited Seodaemun Prison History Hall. I visited it for the first time. People said it was very scary so I felt scared. it is really scary. I saw many types of torture and was surprised so many Koreans  wanted independence from Japan..They only ate like  a beggar and only once a day..My dream has changed, I ' ll help other people like telling them that Dokdo is land of Korea.

Good work, I fixed up some confusing sentences, but good stuff!
