I was born in Korea and grew up there until I was 23 years old. I have many memories of my years in Korea. My grandfather was a very good oriental doctor. When I was 7 years old, when I was running around and playing with my friends in the neighborhood, my grandfather would shout my name out loud and say, "Una, come and take a look at this." He said that if the patient’s earlobe had a 30-degree line, the patient had high blood pressure, and if the patient’s face was exceptionally red, he said there was a problem with the patient’s heart. After looking at the tongue, he said that if the tip of the tongue is red, there is heat in the heart, so this person should receive treatment mainly for the heart. When I was young, I was so interested that when my grandfather identified the patient's pulse, I followed suit. My grandfather seems to have loved me very much because he taught me oriental medicine, which he didn’t teach my father or my father's siblings.

Another memory is that my grandfather always read books in the morning and evening. It was usually a Korean medicine book. When I woke up in the morning and got ready for school, my grandfather's room was always lit, and my grandfather's shadow in the light was always sitting at his desk and reading a book.
