Jeju Island is nature. I feel like I can live here and I think I would love to. The first thing that took me by surprise was how widely its eco-friendly/no chemical agriculture is. There were green fields everywhere. We learned that tangerines are symbolic here because the majority of families grow tangerines and it's easy to access planting them. The taste of my first tangerine that I ate in Jeju was not like an ordinary taste. It felt very clean and a new kind of yummy. Other than tangerines and agriculture, Jeju's geographic landscape is the best experience that I have ever had so far. From climbing Seongsan Sunrise Peak/Mountain to Majanggul Cave and Bijarim Forest, I could really see how natural and preservative Jeju is. There were native plants, no-waste/recycle options, folk villages, and water bodies. Jeju's geographic environment/landscape is marvelous. Seeing clear/clean water and no-factory/no-chemical agriculture made me realize how many old-aged people there are. I like the longevity of the Jeju people, because it shows how healthy they are.
