Brrrr! I am still shivering even after I got home from my daily work out. I came back to Korea about three months ago on December 3rd, 2014 but yesterday and today seemed like the coldest days of this winter season. Ggotsem Chuwee (꽃샘추위: spring colds) is an annual weather phenomenon in Korea that happens normally between end of February to April. During this time, the temperature drops abnormally for about several days and the people who were ready for spring get affected by sudden harsh frost – many end up getting sick and catch a cold.
