One November day in 1947, the great leader Comrade Kim Il Sung visited the canteen of Mangyongdae Revolutionary School.

   At that time the women cooks were making kimchi.

   Kim Il Sung went to a cook and asked her about how to make kkaktugi (cubed turnip kimchi). She said she was going to slice turnip and pickle it with ground pepper, garlic and other seasonings.

   Kim Il Sung told her that kkaktugi would taste good when it is added with pickled oysters, and advised her to mix it with a dash of ground pepper so as to make it less pungent as it would be served to children.

   The cook had never thought of making tasty kkaktugi with oysters abundant in the West Sea of Korea and paid no attention to the taste of young students, regarding that they would like peppery dish.

   One May day in 1949, Kim Il Sung visited the canteen of the school again.

   While carefully looking into a pot, he said: The pork soup is too greasy. It might make some children have loose bowels, and some would feel queasy and dislike eating it.  It is advisable to fry lardy pork with potato, bok choy or leek, instead of making soup. The food will taste wonderful. Kimchi tastes better when it is prepared with various seasonings. A Korean saying goes that good appetite helps digestion. Tasty seasonings make delicious kimchi.

   Later, according to his teachings, the cooks always prepared delicious foods conducive to promoting the health of students.
