Today, I went to Gyeongbok Palace. In there, I could learn about King Sejong and his achievements. King Sejong is the most famous king of the Joseon Dynasty. His most known achievement is the invention of the Korean alphabet. He and his faithful scholars made it.

   King Sejong also supported scientific developments. He supported Jang Young Sil to invent many scientific tools, such as the sundial. King Sejong was interested in expanding Joseon's teritory, too. So during Sejong's rule, Joseon became larger.

   Sejong was enthusiastic about training elites, so whenever he saw smart people with no money and low status, he gave them a place in his cabinet.

   Sejong was a great king. If every king was as good as Sejong, Korea could have been the best country in the world.
